Grow a large crystal from salt. Coloring and storage

An unusual experiment on growing crystals from salt can be done with children. This process is completely safe, as only salt and water is used and no additional reagents are required. Making such a craft with your own hands is quite simple, but you need to consider a few rules.

1 How to grow a crystal from salt - preparing the tool and material

Before you start making crafts, prepare necessary tools and determine the location for the container. The maturation process of the product will take some time, while the dishes cannot be moved and tilted.

The main component for the formation of a crystal is salt. To get a smooth and transparent surface on the craft, use sea salt. It does not have impurities and small debris, like table salt.
Crystal formation will occur in water. It should also be well cleaned of impurities. It is best to pour distilled water or boil the liquid and filter.
The utensils for the experiment should not be metal. Since it can oxidize due to the action brine. The volume of the growing dish does not matter and is only limited by the size of the desired crystal.
Keep the container free of debris and debris. They will prevent the growth of salt on the main crystal. Therefore, before the experiment, the dishes should be thoroughly washed and dried.
As a base, you can use a thread, fluffy wire, dried twigs or a large piece of salt.
In addition, you will need: a wooden spoon for stirring, a piece of gauze or a bandage, paper towels, colorless nail polish, a saucepan and a pencil.

2 How to grow a salt crystal with many facets

The initial stage of the experiment involves boiling the liquid. Therefore, help the children warm the liquid so that they do not burn themselves.

Prepare 120 ml. purified or distilled water. Pour it into a saucepan, put on the stove and bring to a boil.

Decide on the type of salt to form the crystal. So with the help of ordinary table salt, the craft is formed within a few days, sea salt forms a crystal in 1-2 days, and with iodized salt you will have to wait a very long time for the growth of the product.

Prepare a saturated salt solution. You can understand its readiness by grains that could not dissolve in water. To do this, add salt to warm water and stir the solution thoroughly. First, add half a glass of salt. If the water is clear without grains, then add another quarter cup.

Pour the solution into a dry and clean container. Make sure that the sediment stays in the pot, otherwise it will fall to the bottom of the jar, and will reduce the growth of the main crystal.

At this stage, a dye can be added to change the color of the crystal. But do not add too much of it, as in large volumes the tool will make the craft brittle.

Prepare the thread for the warp. It is desirable that it be thick with a rough surface. Tie it to a pencil or a long skewer. Their size should be larger than the diameter of the container for growing a crystal and with edges for stability.

Measure the desired length of thread and cut it. Do not let it touch the bottom of the container.

Position the pencil on top of the container. Make sure that the thread does not stick to the walls of the jar.

Place the brine container on a flat surface. If you want to grow a crystal with large branches, then keep the liquid with the thread in a warm place. To form a crystal with smooth surfaces, put the container in the cold.

Now you just have to watch the growth of the crystal.

3 How to grow one big crystal from salt

To get a large crystal with smooth edges after the experiment, it is necessary to use a slightly different technology.

Prepare a concentrated salt solution as in the previous paragraph. Pour it into a container. But for this method growing diy choose a flat and wide container. So a large crystal will not be able to connect with the rest, smaller parts.

Leave the container with the solution for 2 days for the formation of small crystals. Then pour out the water and choose the most suitable piece for growing.

Tie a small crystal to the fishing line. IN this case it is necessary to use a smooth thread or thin wire (fishing line) so that salt grains cannot be fixed on it.

Prepare a saturated salt solution again. But this time, do not bring the water to a boil, but only warm it to room temperature.

Lower the crystal on the fishing line into the prepared container and pour the saline solution in a thin stream. Secure the fishing line to the surface of the container with a pencil. In this case, the crystal should be located in the center of the container.

Growing a crystal in this way will take much longer than the previous option. Therefore, every two weeks, prepare a new salt solution and be sure to filter it before pouring it into the container.
When the crystals have grown to the desired size, remove them from the liquid, dry them and be sure to cover them with a thick layer of colorless nail polish. It will not allow water to evaporate, which will make the craft more durable for a long period.

It is very easy and safe to conduct an experiment on growing a crystal from salt at home. But to obtain the desired effect, strictly follow the rules specified in the article and do not forget about the finishing of the product.

Do you like to conduct scientific experiments and want to involve your children in this? Most The best way for this - try to grow a crystal together from ordinary salt, which everyone in the house probably has.

Safety regulations

Experience is based on chemical reaction saturated salt solution. Both cooking and sea are used almost every day in everyday life, it will not harm you. But still try to work with gloves and a scarf. This will prevent the ingress of foreign objects into the liquid - dust, hair.

If you have unhealed wounds or burrs on your hands, you need to be very careful, as the solution can corrode the skin in damaged areas and cause acute pain.

In order to grow such a crystal at home, you do not need any laboratory equipment. Everything you need is at your fingertips.

Regular salt crystals should have even, large faces

Do not add natural or artificial colors. This makes no sense: the salt crystal will still grow colorless.

How to grow a crystal

So, water and salt will act as reagents in the experiment, and the equipment will be:

Note! Jars or glasses must be absolutely clean. Any mote on their inner surface can become the basis for the growth of additional crystals that interfere with the main one.

Solution preparation

The germ of a crystal of sea or common salt

Prepare the embryos on which the crystals will grow. They should be large so that you can easily attach them to a thread.

The easiest way to make a selection is as follows: pour salt into the salt shaker and shake until all the small crystals fall out. Those that did not go through the holes of the salt shaker and remained inside are great for our purpose. Choose the largest of them, with a shape close to a rectangle, with a minimum of deviations.

Try to choose the largest and evenest crystals as the embryo of the future crystal

Fix the selected embryo on a thread, and, in turn, wind it on a stick or pencil so that over time it will be easy to adjust the immersion depth.

Height

The main and longest phase of the experiment begins. In a saturated solution poured into a second jar, immerse the embryos, wrap the container with something warm so that the liquid cools more slowly.

If the solution was sufficiently saturated and clean, the embryos will increase slightly in a day. Otherwise, they will dissolve.

Now cover the top of the jar with paper to avoid dirt and dust, and leave for 3-4 days. Water will gradually evaporate, and salt will precipitate, growing on the embryo and ensuring the growth of crystals.

It is at this stage that mistakes made in the preparation process may appear. For example, you could incorrectly fasten a loop of thread to a crystal, and it will simply grow into the middle. To avoid this, fasten the embryo not in a knot, but in a thread loop, both ends of which are brought out. After the growth process is over, pull the ends of the loop one by one to loosen the clamp, and remove the thread.

You can set any shape to the crystal during the growth period

If you want to grow a crystal quickly, take it out of the container after a few days. Over time, it should already increase in size. Prepare a new saturated salt solution and lower the crystal there again. Some experts advise simply adding the required amount of salt to the jar and mix thoroughly.

How to make a crystal at home (video)

As you can see, growing a crystal is not that difficult. The main thing is to adhere to the technology and follow the recommendations. Although this process is not a quick one, in the end you will get beautiful souvenirs that can be used as decoration or a gift. Tell us in the comments about your experience and what difficulties you faced. Good luck!

Growing crystals at home is a very long, laborious and painstaking process, but it is very exciting and definitely worth the time spent. This experience is very popular with children, and most of the methods below are completely safe. So, consider the main ways to grow crystals at home.

How to grow a crystal from sugar at home

It is best to start your experiments on growing crystals at home with the most interesting and enjoyable ones. The easiest way to grow a crystal is from sugar, and if you do this experiment with children, they will be able to taste the fruits of their creativity at the end of the process.

In order to grow a crystal from sugar, we will need:

2 glasses of water;
5 glasses of granulated sugar;
wooden skewers;
paper;
small saucepan;
several clear glasses.

The process of making a crystal begins with the manufacture of sugar syrup. To do this, take 1/4 cup of water and two tablespoons of sugar. Mix, bring on fire until syrup is obtained. Dip a wooden skewer into the syrup and sprinkle with a little sugar. The more evenly the skewer is sprinkled, the more ideal and beautiful the crystal will come out. In a similar way, we make the required number of blanks and leave them to dry completely, for example, overnight.

Some time has passed, our skewers have dried out and now we can move on to the next part of the experience. Pour 2 cups of water into a saucepan and pour 2.5 cups of sugar. On low heat, stirring constantly, turn our mixture into a sugar syrup. Stirring must be carried out carefully, until the sugar is completely dissolved! Add the remaining 2.5 cups of sugar and also, until completely dissolved, cook the syrup. After that, leave the syrup to cool slightly, this will take approximately 15-20 minutes. This time we continue to prepare blanks from skewers, the basis for our future crystal. We cut paper circles a little larger than the diameter of our glasses and pierce the resulting circles with chopsticks. The main thing is that the paper is firmly fixed on the skewer. The paper will act as the holder and lid for the glass.

Pour the cooled, but still hot syrup into glasses. At this stage, a little food coloring can be added to the syrup, then the crystal will eventually turn out to be colored. We lower our blank (a stick with a circle of paper) into the glass and leave it alone until the crystal ripens. It is important not to touch the walls and bottom! Well, we do the same with all the remaining blanks.

It will take about a week to grow a crystal. This is a very interesting and exciting process that children really like. Every day the crystal grows and takes on its individual shape. Some crystals grow faster, some slower, but the bulk matures in exactly 7 days. The resulting sugar crystal is very good to use with the whole family at a home tea party or just nibble in moments of blues! So, entertaining chemistry is not only interesting, but also tasty;).

How to grow a crystal from salt at home

Growing a crystal from salt at home is a fairly simple process, but it requires patience and care. However, the result of the experiment exceeds all expectations. We will need:

pure water;
pot;
2 glass jars;
salt;
strong thread.

We heat water in a saucepan, we heat it very much, and do not bring it to a boil, the experiment will not work in boiling water. After heating the water, we gradually begin to pour salt into it, stirring constantly until the portion of salt is completely dissolved. Then add more salt, stir until dissolved. And so on until the salt ceases to dissolve. Pour the resulting saturated saline solution into a jar and let it stand well for a day. The next day we will see a lot of small crystals of settled salt in the jar. We choose the most beautiful and largest of them, carefully take it out and tie it to a thread. Carefully pour the solution into an empty jar, making sure that the settled crystals do not fall into a new vessel. Then we lower the crystal on a thread into a filtered saline solution and stock up on patience. After 2-3 days you will notice an increase in the crystal, this growth will continue for some time until the end of growth. After you notice that the crystal has stopped growing, you can either end the experiment if you are satisfied with the result, or prepare another saturated saline solution, as we did above, and lower our crystal there. By the way, if you often change the salt solution, then the growth of the crystal will be faster.

It is very important not to cool the solution on purpose and not to shake it, in this case crystals of an imperfect shape are obtained. Also, do not add any dyes, the crystal will not be colored, and the experiment will be ruined.

How to grow a crystal from copper sulfate at home

Growing crystals from blue vitriol at home, this is the next level of complexity, in which it is required to comply with safety requirements and children can only perform it under adult supervision.

For the experiment we need:

water, preferably distilled;
glass jar;
copper salt (copper sulfate or copper sulfate, which can be bought at a gardening store).

Before buying, be sure to consider the substance, it should be a bright blue homogeneous powder. In the presence of lumps and green blotches, it is better to refuse the purchase. It will go to summer residents on the farm, but we, novice chemists, will not.

So, the correct vitriol is purchased. Pour about 100 grams of powder into a glass jar and pour a little hot water, stirring constantly. We must get a saturated solution in which the copper salt can no longer dissolve. Filter the solution and put it in the refrigerator. The next day at the bottom we will find many crystals. We select a couple of the largest and most beautiful and place them in a container with a filtered solution. Before that, we act with crystals in the same way as in the previous experiment with table salt, namely, we fix it on a thread and lower it into a jar. We cover the vessel with thin paper and stock up on patience. Growing a crystal from copper sulfate takes several weeks. After the formation of the crystal is completed, it must be carefully removed, rinsed with cold running water and coated with colorless nail polish.

Ordinary table salt can be turned into an interesting art object, the process of creating which will be exciting for children and adults. Do not miss the unique opportunity, without leaving your home, to observe one of the natural phenomena - the formation of crystals.

Required fixtures and materials

We carefully prepare everything you need to grow a crystal from salt. Everyone in the house will always have everything you need for this work. It has been noticed that a larger crystal grows in a larger capacity, but in this case a lot of salt will be needed:

We take coarse and clean salt. Impurities in it are not allowed, as they will interfere with the formation of crystals correct form. You can use sea salt, despite the complex chemical composition.
It is better to use filtered or distilled water.
2 containers: made of glass to observe the process and to heat water on fire.
Stick (pencil, ruler, etc.).
Thread or thin copper wire.
Funnel.
Filter paper (gauze, cotton wool) is used to filter the solution.
Napkins.

Growing preparation

The higher the temperature, the more the substance dissolves in water. A seed is added to the resulting supersaturated solution, and upon cooling, the molecules adhere to it. Growth begins, depending on how much substance at high temperature dissolved and how much "precipitated" when it was lowered, for example: 2 g of sodium chloride compared to 50 g of copper sulfate.

Unlike other substances, the solubility of table salt is very high; when cooled, the sticking of the substance is minimal, but over time, more and more molecules are added and salt objects increase in size.

The instruction on how to make crystals from salt is quite simple and does not present any difficulty. We bring the water to 80-90 oC, remove from the stove. Gradually add salt (38 g per 100 g of water), constantly stirring, until it begins to dissolve more.

It turns out a supersaturated solution, the salt from which will easily crystallize when it is cooled. Lowering the temperature slowly gives the best result.

We place filter paper in the funnel and pour the contents into a glass container after 30-60 minutes. As a result, we remove all small crystals that can interfere with the main process, and get rid of impurities.

We make a notch on a stick for a more stable fixation. We tie one end of the thread (wire) to the notch. At the other end, we tie a knot or hang any small object on which the molecules will build up.

We lower the thread into the middle of the container. From the wire, you can make complex shapes that will become overgrown with crystals. In the photo of salt crystals you can see a variety various forms depending on the matrix seed.

crystallization process

We cover the top of the jar with a napkin: no foreign impurities should get into the water solution. We place it in a permanent place without temperature fluctuations and try not to move or shake it. Maintaining the same level in the liquid, periodically carefully add a saturated solution of sodium chloride.

Visible shifts are soon observed and after a month a small polycrystal can be seen. The longer it is in solution, the larger it becomes.

At the air-water interface, crystallization occurs more intensively. Variations in the movement of such a seed makes it possible to obtain salt "products" fairly quickly.

And how to make a single crystal from salt? Is it possible to? Experts say that a crystal close to the natural rectangular shape can be obtained quite simply.

In a package of table salt, we select a large crystal and put it on the bottom of the prepared saline solution. Sea salt, as a larger one, is even more suitable for these purposes. To speed up the process, it is transferred to a new saturated solution after a few days. They follow the shape and periodically scrape off excess sticking, trying to keep the shape.

You can see a single crystal much faster: individual crumb crystals appear at the border of air and water in a jar. Transparent, regular shape, they are clearly visible under a magnifying glass.

Coloring and storage

The resulting crystals are dried and coated with a colorless varnish for better preservation. Paint them with different color varnishes.

They will look aesthetically pleasing on a special podium, while being protected from destruction. IN saline solution no dyes are added, as they can only interfere with crystal formation.

The question is often asked: "Is it possible to get a crystal from salt in 1 day?". We hope that the above has already been answered. However, experiment, try, but remember how much time nature spends on growing its miracle!

Photo of salt crystals

Much has become possible for modern man: nanotechnology, artificial insemination, the study of distant galaxies. What can we say about the cultivation of minerals at home. Yes, yes, each of us today can grow a real crystal in our kitchen without laboratory equipment and scientific knowledge. All that is required is ingenuity, patience and a few improvised materials.

Crystals, regardless of whether they are natural or artificial, amaze with their beauty, versatility and unusualness. That is why interest in home growing crystals is increasing. They are grown in the most unusual shapes and colors, using simple ingredients such as salt, soda, citric acid, dyes, etc.

You can grow the most beautiful and unique crystal for yourself different methods by choosing the one you like best. There are even special kits on sale for fans of home experiments, with which you can get crystals of simply incredible shapes.

Here are some photos of finished crystals that amateur chemists post online:

To understand the essence and get the most fantastic crystal, you should watch a detailed video tutorial, and only then proceed to the unusual process of growing crystals.

Instructions on how to grow crystals

Growing homemade crystals is a simple and exciting process if you study the rules of the experiment in advance and prepare the necessary materials. The only negative is that the crystal grows for a rather long time, on average it takes at least a month.

The formation of a crystal lattice, its growth rate, color, density - all this depends on the quality of the prepared solution, the selected dishes, humidity external environment. These details must be taken seriously. But the first thing to start with is the selection of inventory.

To grow a beautiful crystal you need:

Crystal container. This is a kind of incubator that must comply with the rules: it must not oxidize, give off color, and deplete the smell. The best option is glass or enamelware. We exclude metal, clay, plastic dishes immediately. As for the size, there are no restrictions: it is important what size you need a crystal.
Stick for stirring the solution. Here again, the emphasis is on the material - we choose wood or glass.
Paper. In the process of growing, you will need white napkins good quality or filter paper.
The main component for the solution. It can be salt, sugar, soda or something else. This product is selected in accordance with the selected recipe.

Although solutions of different substances are used to grow crystals, the essence of the process itself is almost identical in all recipes.

The basic growing algorithm is as follows:

Salt or other ingredient is dissolved in hot water until a concentrated solution is obtained.
The seed base for the crystal (this may be a large piece of salt) is washed in water and immersed in the prepared solution.
The container with the solution is tightly closed. Remove the lid after about 24 hours. Somewhere in the 3-4 week, a large crystal will already be noticeable.
As soon as the top of the crystal emerges on the surface of the solution, the liquid is drained, and the crystal is carefully removed from the container.
Then the crystal is dried and kept in a place protected from water and its beauty is admired.

How to grow a crystal from vitriol at home, step by step instructions

If you don’t surprise anyone with a colorless crystal, then a bright blue crystal will definitely become a real surprise. To create such beauty, a special ingredient is used - copper sulfate. It gives a brighter and more natural shade of blue than food coloring.

This substance is sold in stores with goods for the garden and garden. It is a chemical substance, so it is not suitable for creativity with children.

If stick next instruction, in a couple of weeks you will grow a gorgeous dark blue crystal:

Pour distilled water into a glass container.
Dissolve copper sulfate powder in it until the granules no longer dissolve in water.

Dip a simple thread into the solution, fixing one edge above the container. Wait a few hours for small crystals to form on the thread.
Choose the one you like best and leave it on the thread, and disconnect the rest and set aside.

Lower the thread with the crystal again into the solution, fixing the structure so that it does not touch the bottom of the container. Give the crystal a few weeks and it will grow blue.
After removing the crystal from the water, dry it and cover it with a colorless varnish to ensure its safety.

How to grow a crystal from salt quickly

Crystals grow well from salt, but most recipes call for plain table salt. It is certainly suitable, but if you are not very patient or you need a crystal as soon as possible, we advise you to use sea salt. It will not only accelerate the rate of formation of a crystal array, but also make it much stronger. But, no matter what kind of salt you take, appearance crystal will remain unchanged - it will be large, white, slightly transparent and, of course, will resemble salt of a bizarre shape.

Let's start growing a salt crystal:

Take boiled spring or filtered water, pour into a glass jar.
Mix it in a lot sea salt, and when its crystals refuse to dissolve, strain the solution through cheesecloth.

Pour the solution back into the jar, select a salt crystal big size, tie a thread to it and lower it into the solution. Then cool the solution quickly (this will accelerate the formation of small crystals on the base).

Wait a week to a month depending on the size of the crystal you need.
Wipe it dry with a napkin, if desired, treat it.

How to grow a crystal from sugar

Sugar crystals are not just a masterpiece of homemade art, but also an unusual delicacy. Just imagine that you will become the creator of edible crystals! Just remember to use the highest quality products.

So, let's begin:

Prepare simple sugar, you can use food coloring if you wish, you will also need wooden sticks, water and a few napkins.

Take 2 tbsp. water and 5 tbsp. sugar, but we will not use them immediately. In a saucepan, heat ¼ tbsp. water and 2 tbsp. l. sugar - you will get a sweet syrup.
Pour a handful of sugar on a clean napkin and roll the sticks soaked in syrup in it. Make sure that the sugar sticks tightly around the entire stick, otherwise the crystal will be asymmetrical.

Let the prepared sticks dry well so that the sugar does not crumble.
While the blanks are drying, take a pan, send 2.5 tbsp. sugar and 2 tbsp. water, boil the syrup. When all the sugar has dissolved, pour out the rest of the sugar and boil the syrup for 15 minutes.
Take several sheets of paper in the form of a square. Pierce them with chopsticks in the middle.

Then quickly pour the syrup into glasses, drop a few drops of multi-colored food coloring into each of them and immediately dip the sticks into them. The workpiece should not reach the bottom or touch the walls of the glass.
Thanks to the sheet, the stick will be securely fixed, in addition, the paper will be a shield that protects the syrup from the penetration of the saw and moisture.

Your crystals will grow in 7-14 days and will be quite edible even for kids. True, provided that natural dyes were used.

How to grow a crystal from citric acid

To grow a crystal, you will need about 180g of citric acid for every 100g of water. Immediately make a reservation that the process is more complicated than in the case of using salt or sugar.

Growing process:

In water (100 ml) at a temperature of 20⁰С, dissolve citric acid (130 g). During operation, the container with the solution will need to be slightly heated so that the temperature is stably kept at 20⁰С. To do this, you can use another container with hot water, in which you can immerse a glass of citric acid. It is advisable to control the process with a thermometer.
Then, within a week, you need to add citric acid, until the moment when it stops dissolving. For this, the remaining 50 g of citric acid is enough for you. The solution will become like thick jelly, and small crystals will appear at the bottom.
At this stage, strain the solution. Wrap one crystal with a fishing line and immerse it in a seed solution.
After 7-10 days, the crystal will reach 10-12 cm in diameter. You can pull it out, dry it and varnish it, or continue growing it.

A citric acid crystal is very sensitive to temperature changes and can crack, so it needs to be grown in stable climatic conditions.

How to grow a colored crystal

If growing crystals from food products already successfully mastered, you can aim at a homemade ruby. Of course, it will not be real, but no less attractive and bright. The chemical substance Potassium hexacyanoferrate (III), which is popularly called red blood salt, will help to get such a pebble. You can buy a substance without problems in an online store or a store with goods for the chemical industry. The crystal grows for about three weeks. At your discretion, you can grow a single crystal or a garden of many small crystals.

The process of growing domestic rubies:

Boil 175 ml of water, dissolve 100 g of red blood salt in it. The water temperature should not be lower than 90⁰С.

Now, if you need a single crystal, take a small crystal of ordinary salt, wrap a fishing line around it, use a wooden stick or pencil to fix the fishing line with the crystal on the glass so that it is immersed in the solution.
If you want to grow a crystal garden, take a smooth stone, granite is better, lower it to the bottom of the container with the solution.
Every day the crystal will increase. After three weeks, the crystal will begin to "peep" out of the water. At this point, it must be removed from the container, dried and covered with nail polish.
It is important to remember that red crystals are very fragile, so you need to work with them as carefully as possible.

How to grow a beautiful crystal

It is possible to quickly grow a crystal of a beautiful regular shape from aluminum alum. If you don't know what it is, we'll clarify: it's medicinal product(double salts) to stop external bleeding and relieve inflammatory process. It is sold in a pharmacy and costs a couple of rubles.

The process is pretty simple:

Buy to get started required drug in a pharmacy. It looks like this:

Boil 0.5 l of water, dissolve in it 6 tbsp. l. alum.
Now it remains only to wait. The main thing is that until the crystals grow, do not disturb them: do not stir the solution, do not shake the container.
After a week, the crystals will noticeably grow:

Now select the seed crystal, make a hole in it, fix the thread, the other end of which is tied to the stick.

Dip the host crystal into the solution and wait 1-2 weeks. Its shape in the form of an octahedron will remain the same, but the size of the crystal will increase significantly.
You will get such an exclusive pendant:

How to grow a crystal in two days

It is impossible to grow the right crystal with beautiful edges from improvised substances in 1-2 days. At best, you will get a lot of small crystals spliced into one bizarre figure. But you can easily solve such a dilemma - buy a ready-made kit for growing crystals in two days. You can find it in any art store. The process is clear and accessible even for children. How to grow a radiant crystal in 48 hours will tell the video:

How to grow a crystal on a thread

To grow crystals on a thread, you need soda. Before starting the process, make sure all work surfaces are clean, as even the smallest speck can spoil all your efforts. To work, you will need two glass glasses, a pack of soda, woolen thread, boiling water.

Soda crystals on a string - growing:

Half fill the prepared glasses with boiling water. Send 6 tsp to each of them. soda.
When the soda dissolves, add another 3 tsp. powder and so on until it ceases to dissolve.
Take a thread 35 cm long, fasten a paperclip at its ends. Place glasses with soda solution in one row, placing a saucer between them, immerse the ends of the thread in glasses.

How to grow a crystal in an hour

How to grow a crystal from potassium permanganate

Diamond-shaped crystals of a beautiful dark purple hue grow from potassium permanganate. The growing process is the same as in the case of using salt or sugar. But the crystals are much more interesting.

How to grow:

Take 100 ml of water. Its temperature should not be lower than 20⁰С.
Dissolve 6-7 g of potassium permanganate in this amount.
When the solution becomes homogeneous, dip a salt crystal fixed on a fishing line into it.
Now, as usual, wait a few weeks watching the purple crystal grow.

How to grow a green crystal

Knowing the basics of chemistry, it is easy to grow a homemade crystal of an exclusive green color. Of course, the easiest way is to buy a special set in the store, but we suggest going the other way and conducting a real experiment.

Growing:

In the Garden and City store, buy Ammophos fertilizer based on ammonium dihydrogen phosphate. This substance will be the seed for growing a large crystal.
Take a small ball of styrofoam, wrap it with woolen thread like a ball.

Sprinkle the ball with Ammophos powder so that large crystals grow. Drop the ball into the empty glass.

Send 40 g of Ammophos and 10 g of green food coloring to another glass, pour 50 g of boiling water, mix everything and pour into a glass with a ball.
It is important to pour liquid along the edge of the container so as not to wash off the Ammophos solution from our ball. You need to fill the glass by ¾ because the ball will float to the surface (this is an important condition).
Now make a cylinder from an A4 paper sheet, put it on a glass, cover the structure with a napkin on top.
Already on the fifth day you will grow an excellent crystal.

Growing crystals at home will be something special for each of you. Someone will get involved in an unusual hobby, collecting their collection of crystals, someone will have fun with children, and someone will improve their knowledge of chemistry. But, in any case, you will have an informative time. Successful experiments!

Crystals have attracted man since ancient times. Almost all precious jewelry stones, with a few exceptions, are minerals with a clear crystal lattice. Modern technologies enable the cultivation of artificial gems, which outwardly do not differ from the real ones, have the same structure. Surprisingly, not only minerals, but ordinary grains of salt or sugar are also crystals that can grow. How to make salt crystals yourself? Let's talk about this in more detail.

First you need to choose the substance that you want to form into a crystal. Experiments at home have shown that the easiest way is to use ordinary table salt. This method has an undeniable advantage - all the necessary components are literally at hand, without requiring the purchase or search for special components. Read the instructions carefully before starting the experiment. Different salts are suitable for the “little miracle”:

marine;
cooking;
copper or iron sulfate;
potassium chloride;
potassium alum;
potassium permanganate.

Exercise extreme caution when handling the substances used. You must immediately decide what result you want to get - one large single crystal or several smaller ones. To do this, you will have to use different technologies. Note that the growth of single crystals is simpler in execution. Important: the container in which our beautiful stone grows is unacceptable to shake and move, otherwise it will turn out to be of irregular shape. It is forbidden:

without reason to remove the crystal from the vessel;
use food coloring to add color;
paint the surface of the finished "product" with paint.

How to grow a salt crystal at home

So you've decided to learn how to make a salt crystal. For a little preliminary practice, a ready-made crystal growing kit, which is sold in children's stores, is suitable. You will be able to carry out this process with your child. He will definitely enjoy the job. There is an express way to get what you are looking for in 1 day, but then you will get not one large, but several small crystals fused. If you are ready for the expectation and impressive results, we will tell you how to grow a crystal from table salt.

Necessary materials and tools

For the intended experience, it is necessary to prepare a set of required materials, which should contain:

two transparent containers (so that we can observe the growth);
the substance that we will use for growing (in our case, this is table salt);
stick or tablespoon;
funnel;
filter paper;
a thread, and better, if any, a thin copper wire;
lots of time and patience.

Step-by-step instruction

All necessary materials prepared, it's time to start making a grain of salt with a magic stone. What is the basic principle of how a small crystal becomes large? A small grain is added to a saturated solution of a substance, and the molecules begin to stick to it. The crystal is growing. In order for the molecules to stick, you need to cool the liquid or evaporate it. The slow cooling method achieves a faster result. We bring to your attention instructions on how to make crystals from table salt:

In a glass container (it is better not to use a plastic one), we prepare a saturated saline solution. IN hot water add salt, mix thoroughly (for 100 grams of water heated to a temperature of 80 °, 36-38 grams of salt are required).
The finished solution must be allowed to cool. An hour after that, it must be filtered - using a funnel with cotton wool or special filter paper.
The composition that has stood for several hours is filtered again.
We tie a larger grain of salt to a copper wire or thread and lower it inside the container. It should be suspended, not touching the bottom. The jar should be covered with paper to avoid dust.
After a day or two, the bottom, walls, and the wire itself are overgrown with many small crystals. We take the second vessel, carefully move our embryo there and pour the liquid.
The remaining crystals are again filled with water, and then all the time we maintain the liquid level in the jar with a growing crystal. Approximately once a week, the solution must be filtered from the precipitated crystals.
After a few days, growth will become clearly noticeable. Continue growing as long as you want until you get the desired result. Then carefully remove the miracle stone, rinse gently and cover with colorless nail polish to give strength.

Have you ever seen crystals? If the answer is yes, then you will not deny that this is an unusually interesting sight. The crystals shimmer so beautifully sunbeams, and their faces often form amazing patterns. Do you know that they can be created not only by nature, but also by people? The question is, how to grow a crystal at home?

What is a crystal?

It should be remembered that a crystal is a loose concept. There are single crystals and polycrystals. Here you can do without complicated scientific definitions. Examples of single crystals are diamonds, topazes, sapphires, emeralds and other precious stones that are inserted into jewelry. And the definition of "polycrystal" speaks for itself. These are several intergrown single crystals. All these varieties of crystal are quite easy to grow at home. Now you will learn how to create a single crystal.

How to grow a single crystal from salt?

Please note that this process will take more than one week, because such a crystal grows very slowly. Many, having heard the phrase “from salt”, immediately draw in their imagination a small grain from a bag of table salt. Of course, sodium chloride can be made into a crystal, and it is most often used for this purpose. But as a result, it will turn out colorless, almost transparent. If this is what you are striving for, please grow a crystal from table salt. But you can make it green, and blue, etc., you just need to take other salts. So, green crystals are formed if copper chloride or nickel sulfate is used. A blue crystal will be obtained from copper (II) sulfate. There are also other color options.

What you need for the experiment:

Clean container (preferably a jar or saucepan)
Selected salt
A stick to stir the solution
Filter paper
Colorless varnish
Button or properly developed salt crystal (for "seed")
Thread

Progress

1. First you need to prepare a saturated solution of the selected salt. Pour it into a pot of water (preferably distilled). Add and stir the salt until it no longer dissolves. Then remove excess salt with filter paper.

2. Distilled water can be made by yourself. To do this, take plain water and put it in a saucepan on the fire, covered with a cone-shaped lid. Gathered as a result of boiling on inside Drain the lids of the pairs into a separate container. This will be distilled water.

3. Then you should make a "seed", which will be a kind of "embryo" of the crystal. After all, as you know, not a single object appears from nowhere. If the choice fell on a button, then it is necessary to soak it in a saturated salt solution, and then dry it. If you prefer a crystal, then when choosing it, you need to consider the following:

Sizes (approximately with the same button)
No damage (scratches, broken edges, etc.)

4. That's it, the "seed" is ready. Now tie it to a thread and lower it into a jar of saturated solution.

5. Then place the container with the solution and "seed" in place with constant temperature. Now it remains only to wait. The crystal will begin to grow somewhere in 3 days.

It is recommended to update the solution every week according to the above scheme. When the crystal reaches right size, pull it out and dry it, and then grease it with colorless varnish (this is necessary so that the fruit of the work shines beautifully and is protected from scratches).

You can make a complex single crystal. To do this, when the size increases to about 2 cm, lower the crystal into a saturated solution of another salt. Change the chemical medium every 2 weeks. It is recommended to use as many salt solutions as possible. If the resulting crystal is cut with a jigsaw, you will see that the colored layers replace each other.

It will take approximately 3-4 months to create a single crystal of average volume. The larger the desired size, the longer the growing period. A polycrystal can be made in a matter of minutes, but more on that we will talk perhaps another time.

Happy growing salt crystals!

Experiences such as growing a crystal with your own hands will help you feel like a jack of all trades - you will learn how to make beautiful jewelry for home, sweet lollipops and help your kids learn the basics of chemistry.

Use of crystals

Such an idea how to grow a crystal is a great opportunity to study Chemical properties different substances. If you have children at home, be sure to challenge them to grow a crystal at home - not without your help, of course. It will be interesting for the children to observe the progress of work, comprehending chemical science in such an exciting way.

Some experiments will also help you get decorative details to decorate individual compositions - for example, salt crystals can be excellent decorating materials.

However, it must be remembered that many of the materials used are extremely poisonous - they should not be touched by hands or inhaled vapors. Such substances are not suitable for use in Everyday life- They can only be used for experiments.

Growing crystals can be chosen as a hobby, an exciting activity, because in fact the creator never knows what kind of crystal will turn out in the end.

Types of chemicals

At home, you can grow a crystal from a variety of substances. Some of them require special processing: you can work with them only under certain conditions - at a special temperature, lighting, etc. These include the following materials:

Mohr's salt;

blood salt;

various alums;

nickel sulfate;

ammonium nitrate.

If you are just starting out with how to grow a crystal at home, it is better to postpone using them.

However, many work mixes, such as table salt, can be found in any home. With them, it is recommended to start work for beginners.

Salt

There is nothing easier than growing salt crystals at home!

To operate this product, you do not need to use any special accessories or equip workplace with supernatural conditions.

blue vitriol

Another easy option. Before growing a crystal from copper sulphate, the substance can be bought at an amateur gardener's store - it is sold as a fertilizer.

From the master classes below, you will understand that working with vitriol is as easy as growing a crystal from salt. The only difference is that the mixture is an active saturated salt substance, so it is undesirable to conduct experiments using running or any other water - only distilled water, which you can find in a pharmacy, is suitable.

Sugar

The only substance that can be eaten after the experience! Experiments with sugar are completely harmless, so you can safely teach your children how to grow a crystal, using his example.

The result should be delicious sugar candies in the form of frosty crystals - an original replacement for cockerels on a stick.

Safety regulations

Despite the fact that novice chemists use mainly familiar solutions, such as salt or sugar, everyone must follow certain precautions - the instructions are presented below.

Allocate special dishes for experiments, from which you will not eat in the future. Neglect of this point can lead to serious food poisoning.
Each substance must be stored in a separate, hermetically sealed package with a mandatory signature of the contents on the bottle. Keep substances out of the reach of children and pets, in a cool and dark place.
Use protective clothing and gloves.
Work with chemicals that emit vapors into the air should be carried out only near powerful hoods.
If acid gets on the skin, be sure to sprinkle the place with a weak alkali (water diluted with baking soda) and vice versa - alkaline solutions are easily neutralized with an acid like citric acid.

Such skills are very useful when working with dangerous chemicals. Over time, you will bring the implementation of this instruction to automaticity and will not worry when you want to use dangerous mixtures instead of ordinary salt or soda to grow a crystal.

salt crystals at home

After the theoretical advice, you can move on to the part where you will learn how to grow a crystal from salt. Prepare water in unlimited quantities - it is better to use distilled water (purified from any additives) so that the substance does not react with any impurities. However, ordinary running water will do.

In addition, you will need a small saucepan, a glass container (jar, glass), silk thread, a pack of salt.

Place a saucepan of water over medium heat. Heat the water, but do not bring to a boil.

In small portions, start pouring salt into the water, stirring constantly. Each time pour a new handful after the previous one is completely dissolved.

The preparation of the solution ends when the salt has completely ceased to dissolve in water - this means that you have prepared a concentrated mixture.

Pour the concentrated composition into a transparent glass container and leave to settle for about a day.

Free time is necessary for all the smallest, undissolved particles to settle to the bottom. In the photo you can see how the salt precipitate is obtained.

Take a thread or string, tie it around a long thin stick that you can put on the neck of a glass container.

The length of the lace should be less than the height of the vessel, so cut off the excess.

Lower the string into the water in a suspended state so that it does not touch the walls of the jar and the sediment at the bottom.

Leave the experiment in this state for 1-3 weeks.

After a couple of days, you will notice an increase in small crystals on the thread. Experience in this case is interesting just by observing how much the crystal grows over a certain period of time.

Instead of an ordinary thread, you can lower a large piece of salt suspended on a thread into a glass. In this case, the substance will grow around it.

You can either grow a crystal of a certain shape, or an arbitrary one. To control the appearance of the substance, apply a thin layer of grease or petroleum jelly to one side of the crystal - you will see that there will be no growth here.

If desired, salt can be replaced with other substances - for example, it is easy to prepare crystals from soda or copper sulphate using the same technology.

How to grow a crystal from sugar?

If you set a goal to learn how to grow a crystal from sugar, you will be pleasantly surprised by the result - beautiful sweet candies that will delight children and pleasantly surprise adults during tea drinking. An interesting option their use is to stir tea with them. So you get both a stir stick and a sugar sweetener.

Prepare a concentrated sugar solution in the same way as in the experiment with salt - the sugar should completely stop dissolving in warm water. After that, pour the hot syrup into a transparent bowl.

When the solution is ready, start preparing the base sticks. Tie one stick to the other crosswise so that the first is lowered into the bowl, and the other is held by its neck.
