How to grow a crystal at home from salt?

An unusual experiment on growing crystals from salt can be done with children. This process is completely safe, since only salt and water are used and no additional reagents are required. Making such a craft with your own hands is quite simple, but several rules must be taken into account.

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

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

• The main component for crystal formation is salt. Use sea salt to get a smooth and transparent surface on your craft. It does not have impurities and small debris like table salt.
• Crystal formation will take place in water. It should also be well cleaned of impurities. It is best to pour in distilled water or boil the liquid and filter.
• The experimentware should not be metal. Since it can oxidize due to the action of brine. The volume of the growing dish is irrelevant and is only limited by the size of the desired crystal.
• Avoid debris and debris in the container. They will prevent salt buildup on the main crystal. Therefore, before the experiment, the dishes should be well rinsed and dried.
• You can use thread, fluffy wire, dried twigs, or a large piece of salt as a base.
• Additionally you will need: a wooden stirring spoon, a piece of gauze or bandage, paper towels, colorless nail polish, a saucepan and a pencil.

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

• Prepare 120 ml. purified or distilled water. Pour it into a saucepan, place it 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 product to grow.

• Prepare a saturated salt solution. You can understand about 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 glass.

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

• At this stage, you can add a dye to change the color of the crystal. But do not add too much of it, as in large quantities, the product will make the craft fragile.

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

• Measure the required length of thread and cut it off. Do not let it touch the bottom of the container.

• Place the pencil on top of the container. Make sure that the thread does not stick to the sides of the can.

• Place the container of brine on a flat surface. If you want to grow a crystal with large ramifications, keep the filament liquid in a warm place. Place the container in a cold place to form a crystal with smooth surfaces.

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

To obtain 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 point. Pour it into a container. But for this method of growing the craft, choose a flat and wide container. This way, a large crystal will not be able to connect with the rest, smaller parts.

• Leave the container with the solution for 2 days for small crystals to form. Then pour out the water and choose the most suitable grow piece.

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

• Re-mix brine. But this time, do not bring the water to a boil, but only warm it up to room temperature.

• Dip the crystal on the fishing line into the prepared container and pour in the saline solution in a thin stream. Attach the 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, prepare a new salt solution every two weeks 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, pat dry and be sure to cover with a thick layer of colorless nail polish. It will prevent the water from evaporating, which will make the craft more durable for a long period.

It is very easy and safe to experiment with 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? The best way to do this is to try to grow a crystal together from common salt, which everyone probably has in the house.

Safety regulations

The experiments are based on the chemical reaction of a saturated salt solution. Both cooking and seafood is 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 foreign objects from entering 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 the 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 smooth, large edges.

Natural or artificial colors should not be added. 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:

• two containers (glasses, half-liter cans or not too large pots);
• filter paper;
• thread or hair.

  To grow a crystal, you will need salt, water, threads and some kind of container.

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

Preparation of the solution

1. First of all, you need to prepare a saturated saline solution. Pour water into the jar. It is desirable that it be distilled or at least filtered. Fill the container to about 80%, place it in a water bath.
2. At this time, add salt to the jar. If you use a cookery, an unpleasant surprise awaits you - various debris that will float to the surface. Gently remove it immediately or pass it through filter paper afterwards. Sea salt is sold, as a rule, pure. Just do not take flavored and colored with various additives, this will greatly harm the process.
3. Pour salt with a margin so that the solution is saturated. The recommended proportion is 100 g of product per 150 g of water. Some of the substance must remain at the bottom, because it simply cannot dissolve. Just at this stage, pour the liquid into another jar, at the same time getting rid of small debris and undissolved salt.

   The salt solution must be very saturated

Seed crystal of sea or table 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 in the following way: pour salt into a salt shaker and shake until all small crystals fall out. The ones that didn't go through the holes in the castor and stay inside are fine 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 smoothest crystals as the seed for the future crystal

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

Growth

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 pure, the embryos will slightly increase in a day. Otherwise, they will dissolve.

Now cover the top of the jar with paper to avoid debris and dust and leave for 3-4 days. The water will gradually evaporate, and the salt will precipitate, growing on the nucleus and allowing the growth of crystals.

It is at this stage that mistakes made in the preparation process may appear. For example, you could not attach a loop of thread to the crystal incorrectly, 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 alternately to loosen the grip, and remove the thread.

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

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

Growing crystals at home is a very long, laborious and painstaking process, but it is very exciting and definitely worth the time spent. Children love this experience, and most of the methods below are completely safe. So, let's take a look at the main ways to grow crystals at home.

How to grow sugar crystal at home

It is best to start your experiments on growing crystals at home with the most interesting and enjoyable ones. The easiest way is to grow a crystal 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 cups granulated sugar;
• wooden skewers;
• paper;
• small saucepan;
• several transparent glasses.

The crystal making process begins with making 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 in syrup and sprinkle with sugar a little. The more evenly the sprinkling of the skewer occurs, the more ideal and beautiful the crystal will be. 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 experiment. Pour 2 cups of water into a saucepan and pour 2.5 cups of sugar. Over low heat, stirring constantly, we turn our mixture into sugar syrup. Stirring must be carried out thoroughly 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 about 15-20 minutes. In the meantime, we continue to prepare blanks from skewers, the basis for our future crystal. We cut paper circles slightly 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, you can add a little food coloring to the syrup, then the crystal will eventually turn out to be colored. We lower our blank (stick with a circle of paper) into a 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 the 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 just 7 days. The resulting crystal from sugar is very good for the whole family to use at home tea, or just gnaw in moments of melancholy! So, entertaining chemistry is not only interesting, but also delicious;).

How to grow salt crystal 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 need:

• pure water;
• pan;
• 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, little by little, we begin to pour salt into it, stirring constantly until the portion of salt is completely dissolved. After that, add more salt, stir until dissolved. And so on until the salt stops dissolving. Pour the resulting saturated saline solution into a jar and let it stand well for a day. The next day we will see many small crystals of settled salt in the bank. We choose the most beautiful and largest of them, carefully take out and tie on a thread. We carefully pour the solution into an empty jar, making sure that the settled crystals do not fall into the new vessel. Then we dip the crystal on the thread into the filtered saline solution and be patient. 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 happy 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, the crystal growth will be faster.

It is very important not to specially cool the solution 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 copper sulfate crystal at home

Growing crystals from copper sulfate at home is already the next level of complexity, in which you need to comply with safety requirements and can only be performed by children under the supervision of adults.

To conduct the experiment, we need:

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

Before buying, be sure to consider the substance, it should be a bright blue homogeneous powder. If there are lumps and green blotches, it is better to refuse the purchase. For summer residents, he will go to the farm, but for us, novice chemists, no.

So, the correct vitriol has been purchased.Pour about 100 grams of powder into a glass jar and fill it with hot water little by little, stirring constantly. We must get a saturated solution in which the copper salt can no longer dissolve. We 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 ones and place them in a container with a filtered solution. Before that, we act with the crystals in the same way as in the previous experiment with table salt, namely, we fix them on a thread and put them in a jar. We cover the vessel with thin paper and be patient. Growing a crystal from copper sulfate takes several weeks. After completing the formation of the crystal, it must be carefully removed, rinsed with cold running water and covered with colorless nail polish.

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

Necessary tools and materials

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

• We take coarse and clean table salt. Impurities in it are not permissible, as they will interfere with the formation of crystals of the correct shape. Sea salt can be used despite its 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 a fire.
• Stick (pencil, ruler, etc.).
• A thread or thin copper wire.
• Funnel.
• Filter paper (gauze, cotton wool) is used to filter the solution.
• Napkins.

Preparation for growing

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 of the substance is dissolved at high temperature and how much "precipitated" when it decreases, for example: 2 g sodium chlorine in comparison with 50 g of copper sulfate.

Unlike other substances, the solubility of table salt is very high, upon cooling, the adhesion of the substance is minimal, but over time, more and more molecules join and the salt objects increase in size.

The instructions on how to make crystals from salt are quite simple and not difficult. We bring the water to 80-90 oC, remove it from the stove. Gradually add salt (38 g per 100 g of water), stirring constantly, until it dissolves more.

A supersaturated solution is obtained, the salt from which will easily crystallize when it is cooled. Lowering the temperature slowly gives the best result.

Put filter paper into 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 the stick for a more stable attachment. 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 molecules will grow.

We lower the thread into the middle of the container. Wire can be used to make complex shapes that will become overgrown with crystals. In the photo of the salt crystals, a variety of different shapes can be seen, depending on the matrix seed.

Crystallization process

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

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

Crystallization occurs more intensively at the air-water interface. Variations in the movement of such a seed makes it possible to obtain salt "products" quickly enough.

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 bag of table salt, 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 monitor the shape and periodically scrape off excess adhesion, trying to keep the shape.

A single crystal can be seen much faster: individual tiny crystals appear at the border of air and water in the jar. They are transparent, of the correct form, and are clearly visible under a magnifying glass.

Staining and storage

The crystals obtained are dried and covered with a colorless varnish for better preservation. They are painted with varnishes of different colors.

They will look aesthetically pleasing on a special podium, while protecting themselves from destruction. No dyes are added to the saline solution, since they can only interfere with crystal formation.

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

Growing salt crystals at home is an opportunity not only to quickly observe how similar phenomena occur in nature with other materials, but also to get an unusual craft as a result.

Moreover, such a process is completely safe and does not require any deep knowledge in chemistry or any reagents, any person in the house has all the objects and substances.

How to grow salt crystals at home: materials and equipment

1. The first and most basic ingredient is salt... For the success of the crystal growing process, it is important that it is as pure as possible. Therefore, it is worth giving preference to sea salt, because there is too much small rubbish in the cooking area. It is also not recommended to purchase salt with dyes or other additives.

2. Water, which should also be cleaned as much as possible from impurities. If it is not possible to use distilled, then it is worth at least pre-filtering it.

3.Non-metallic crystal growth tank... Its size can be limited only by the desired crystal size. Important requirements - the material of the container must not stain water or oxidize under the influence of salts. The container should be washed thoroughly. Any foreign objects inside, even if they are small specks, can become the basis for the growth of other small crystals, slowing down the growth of the main one.

4. A small crystal of salt from the pack, a piece of a branch, a leaf, a wire, thread or any other object for the base of the future large crystal. A suitable large lump of salt is easy to find in an almost empty salt shaker. Small particles fall out of it during use, and large ones do not crawl through the holes and remain inside. It is necessary to choose the largest and having a shape that is as close to a parallelepiped as possible.

5. Something non-metallic for stirring the solution - wooden stick, plastic or ceramic spoon, etc.

6. Filter paper or gauze.

7. Paper napkins or toilet paper.

8. Varnish for coating the finished crystal.

9. Patience... It's not enough to know how to grow salt crystals at home, you still have to be able to wait. A little bit decent in size crystal will form not earlier than in 3-4 weeks.

As you can see, no complicated or expensive equipment is required. All these objects and substances are easy to find in the household of absolutely any person.

How to grow salt crystals at home: a sequence of actions

The technology for obtaining a crystal from salt is very simple, besides, the process requires very little human participation, basically it only takes time. A container with clean water is placed in warm water (50-60 degrees, no more needed), and salt is gradually poured into it, constantly stirring the solution. When it becomes saturated, i.e. there will already be so much salt in it that it will not be able to dissolve further, it is poured into a clean container so that the sediment from the old one does not get into it. You can even further clean the solution from impurities by passing it through filter paper or gauze folded several times.

It is possible to achieve the required water temperature for heating the solution even in the absence of a thermometer. To do this, mix freshly boiled boiling water and water at room temperature in a ratio of about 1 to 2.

Further, it is necessary to place (on the bottom or hanging on a thread) an object in the container, around which a crystal will subsequently form.

• For the traditional crystal form, it will be a large grain of salt, which is easy to find in any pack;

• For an elongated crystal, a thread is lowered into the solution so that it does not touch the walls and bottom;

• If you want to get a crystal of a complex and bizarre design, then a small twig or curved wire is suspended on a thread.

Knowing how to grow crystals from salt at home, you can not limit your imagination to objects that are simple in shape. To get not just a crystal, but a truly original craft, you can place a wire curved in the form of a star, snowflake or other similar simple shape in the solution as a base. In principle, you can use absolutely any item that is not subject to oxidation from salts.

Next, the container is covered with a lid, a napkin, a sheet of paper, and in general anything, just to protect the solution from dust and foreign objects. The container with the growing crystal should be stored in a dark, cool place without drafts. Strong mechanical influences on it should not be allowed - too frequent movements, shaking, etc., as well as regular and significant changes in temperature or humidity, i.e. for example, it is not worth placing a crystal in the bathroom, as well as near the stove in the kitchen or near heating appliances.

Naturally, the more a crystal grows, the less salt remains in the surrounding water.Therefore, to speed up the process about once a week - ten days, a new salt-saturated solution must be added to the container. And if the crystal has already grown out of an old glass or jar, it can be transferred to a larger one, taking care not to drop or break at the same time, because it is very fragile.

The crystal removed from the solution is dried from the remaining water by gently blotting it with a soft cloth or ordinary paper napkin. This should be done very carefully, because the crystal is not particularly strong. For preservation, the crystal is coated with household or manicure colorless varnish. If this is not done, then the life of this beautiful object will be short-lived. In dry air, the remaining water will quickly evaporate, and it will crumble into powder, and with excess moisture, on the contrary, it will absorb excess liquid and spread into a shapeless pile of separate small crystals or even into a slurry.

White crystals will be obtained from table salt.

If you want other shades, then you can:

• use a different type of salt (for example, copper sulfate for a deep blue color);

• cover the finished crystal not with a transparent, but with a colored coating;

• add food coloring agents to the solution at the stage of crystal preparation, for example, those used in baking or for Easter eggs. However, such substances cannot give very bright colors.

There will be no fundamental difference in the growth rate and shape of the finished crystal when using table or sea salt. However, in the second case, the crystal will turn out to be denser in structure and will be more durable.

If the crystal grows a little of the wrong shape, then the excess areas can be carefully scraped off with a knife or a nail file, remembering that the crystal is very fragile. It is easy to give the crystal the desired shape if you treat those areas of undesirable growth with ordinary petroleum jelly or another thick fatty substance. If it needs to be removed, it can be done with acetone or alcohol.

In order for the crystal to split, as if branching in different directions, a small amount of glycerin is added to the solution.

Precautionary measures

Table salt is an absolutely harmless substance for humans, because we eat it every day without any health consequences. Therefore, there is no need to follow any safety precautions when growing a salt crystal.

However, so that foreign objects do not get into the solution, the hair should at least be collected, and it is better to cover it with a kerchief, and wash your hands with soap and even wear rubber gloves. And if there are scratches or wounds on your hands, it is simply necessary to put on gloves, otherwise the strong saline solution will pinch strongly. Nothing fatal or harmful, but not a pleasant experience. Likewise, hands are better protected if dyed salt is used and there is a possibility of allergy to these dyes.

But when working with copper sulfate and other more aggressive salts, it is imperative to observe precautions, trying not to inhale the solution, prevent it from getting on the skin, and also be in a well-ventilated room and keep small children or pets away from the container from growing crystals ... The containers used for this chemical experiment should in no case then be used for receiving or storing food, medicines, personal hygiene items, cosmetics, in general, everything that will subsequently be in direct contact with the human body.

How to grow salt crystals at home: reasons for failure

Why did the lump of salt, taken as a base, dissolve instead of forming a crystal around it? This means that the salt solution was initially insufficiently saturated. When preparing it, add a little salt until it no longer dissolves, but precipitates.The diagrams of the solubility of these salts in water of a certain temperature, easily found on the Internet, will help to choose the proportions of food and other salts for preparing a solution.

If, instead of one, several small crystals suddenly grew in the container, then this indicates foreign impurities in the solution. This can be both insufficiently well-filtered water, and litter in salt or a poorly washed container where the solution was poured.

What is the reason for the lack of uniform color of the colored crystal? Perhaps, when adding the dye, it was not stirred very thoroughly. And if the crystal is large, and for it the saline solution was prepared several times, then one of the times the dye was added significantly less or more than the others.

Of course, even knowing how to grow crystals from salt at home and following all the recommendations, you can get not quite what you wanted. This is normal, because the conditions in which the growing crystal is placed and the substances used for this may differ. However, over time, it will certainly be possible to get a handle on, to find the optimal proportions of components and conditions for crystal growth.
