The term "crystal" means a substance in which minute particles, the atoms are arranged in a certain order.They form a lattice - ordered three-dimensional periodic spatial installation.As a result, external crystals have the right kind of symmetrical polyhedra.They can vary greatly in shape and have four to several hundreds of faces which intersect at right angles with each other.
Sol - representative of the family of crystals
One of these solids with ordered symmetric structure is common salt.It is a food product, which occurs naturally as a mineral called halite.Most of it is in the amount of sea water and other sources of salt.If you look through a microscope or magnifying glass grains of salt, you will notice that they have flat faces.A means is in the crystalline state.In this article we will talk about how to make a crystal of salt alone.In fact, it's easy.To understand how the formation of salt crystals, that is, the crystallization process offers an interesting experience to carry out at home.The child is desirable to perform it under the guidance of an adult.Note that the crystal form of the salt may be varied, including cubic, prismatic or any other - more complicated.However rock-salt crystal face always intersect at right angles.
will talk about how to make a crystal of salt: the necessary supplies and tools
Well, let's get to work.What materials and tools we need for this interesting experience?Of course, salt, water, clear glass containers, rope or thick thread, a wooden paddle.You should also prepare a rod ballpoint pen or a pencil.And most importantly - you need patience.The fact that the crystallisation process takes time - about three weeks.How to make a crystal of salt?Take a good salt, without additives.It is desirable to purchase a product purity not less than 98%, otherwise experience may fail.If the salt is a wide variety of contaminants, then a copy will turn ugly and will have flaws.Growing crystals of salt will start with the preparation of highly concentrated solution.Pour into a glass jar or warm water (200 ml) and start adding salt.Do not forget to stir constantly fluid wooden spatula.This is to ensure that the salt is readily soluble.After the solution is ready (which can be determined by the fact that the salt is no longer introduced to dissolve in a glass of water with stirring at normal), heat the mixture.Fill the pot with water, put on fire, podogreem water.Then carefully place it in a glass with a concentrated saline solution and wait until it warms up.
continue to work on growing beautiful salt crystals
then removed our glass beaker from the pan and leave it alone.On rod ballpoint pen (pencil) provides a thread which is tied to a small crystal of salt.Put on a glass rod and immersed in a solution with the string "seed."It is this salt crystals will grow our beautiful exhibit.That's it, now we can only wait.Glass put in a warm place and monitor every day the process of crystallization.In no case can not shake, flip or lift the container with a solution.Gradually the crystal will grow and become large enough.When this happens, you can carefully remove it from the solution.We strongly recommend to dry it with a napkin, but be very careful - your copy very fragile.Trim the excess thread and cover the crystal clear varnish to extend his "life."Now you know how to get salt crystals at home.We hope you'll have to repeat our simple experience.
crystals of sea salt: experience in creating beautiful exhibit
If you want to grow big, smooth and beautiful patterns - pay attention to the following experiment.To work, you will need these materials and tools:
- transparent glass;
- water;
- sea salt;
- paper;
- napkin;
- wooden shovel;
- flat stone of medium size.
technology is the process of growing the crystal.First, pour into a glass of water is not too hot and start to pour into her sea salt, gradually, one teaspoon.Do not forget to interfere with a shovel.The salt should be added to the liquid until it stops until dissolved.Now take a tissue and filter the resulting solution through it.This is done in order to not interfere with the formation of small particles smooth and beautiful specimen.
process of creating a large salt crystals
How to make a crystal of salt: after filtering the solution was put in a small stone (can be replaced by a nut) and put it to cool.Remember, the slower will cool our salty liquid, the larger crystals are obtained.It is advisable to cover the glass with paper and put it in a dark place, protected from drafts.After two or three days you will see how your stone will acquire small crystals.Keep an eye on the fact that the solution is always completely covered the "seed."It should also be a weekly cleaning liquid from dust and unnecessary crystals formed on the bottom of the glass.As the evaporation needed to refill the tank highly concentrated saline solution.Make sure that it was clean and not cold (room temperature).In addition, it is necessary to periodically remove the crust that appears at the bottom of the container.After two to three weeks your crystal reaches about 2-3 cm in length.And in order to get a large specimen, it will take more time - about 6 weeks.
Adjust the salt crystals
Remember that you can not get just beautiful and smooth crystals.In any case takes practice.We recommend that you carefully adjust the crystallization of the samples, removing the build-up is not very nice.This can be done with a sharp knife, scraping them too much.Also, using petrolatum, can stop the formation of facets.If necessary, a layer of petroleum jelly can be removed from the sample with acetone.When your crystal will grow to the desired size, you can carefully remove it from the solution.After that you should gently rub the edge with a napkin.Cover the sample can be hairspray: because your crystal will become less fragile, brittle and permanently retain its beautiful appearance.
original articles from crystals of salt
At home, you can not just grow a normal salt crystals, but also make an interesting crafts.To do this, you need these tools and materials:
- water;
- salt;
- wire;
- thread;
- filter paper;
- Bank - 2 pcs .;
- pan;
- wooden spatula.
The work will start with the dissolution of salt in water.We make it into a liquid in small portions, adding the following after the final dissolution of the only previous one.When the salt stops dissolving, proceed to the next step.Take a pot, fill with water and put the container on the stove in a small fire.It put a jar with brine.We monitor the process of heating.We continue to dissolve the salt, bringing the temperature to 65 degrees.All turn off the gas, but until we take out a jar from the pan.The fact that the temperature difference may lead to the fact that the glass container to burst.After cooling the solution, you can safely get the bank out of the pan.
Filtering solution and crystallization
then proceed to the purification of the solution from the impurities.Take a clean jar and fasten it to the neck of the filter paper.Now carefully pour the solution into a new container.All undissolved salt crystals and impurities remain on the filter paper.We get a clear solution.Now, put the jar with the liquid in a cool place and make the "seed."Take copper wire and perform any of her animal figures, flower, twig, a star.Winding a wire filament.Place the workpiece in a jar with brine, cover with a cloth container, leaving only a small gap.That's all there is to wait until the crystal growth occurs from the salt.After the wire will acquire, it is possible to extract from a solution.This should be done very carefully, because the salt crystals can break.
