GROWING RUBY CRYSTALS AND OTHER ARTIFICIAL STONES AT HOME
Artificial stones have long gained popularity in jewelry. After all, for a jeweler, the value of a stone is determined not only by its deficiency in nature. A number of other characteristics play an important role:
the refraction of light;
weight in carats;
size and shape of faces, etc.
The most expensive synthetic precious cubic Zirconia stone (synonyms: dimanski, dzhevalit, cubic Zirconia, Shelby). Its price is low – less than $ 10 per 1 carat (0.2 grams). But it is worth noting that with the increase in carats the price increases exponentially. For example, a 10-carat diamond is 100 times more expensive than a 1-carat diamond.
Artificial crystals of jewelry stones can be grown at home. Most of these experiments do not need special training, you do not need to equip a chemical laboratory and even buy special reagents.
To gain experience growing crystals, start small. We will share the technique of growing beautiful crystals from everything you can find in your own kitchen. You do not need additional equipment, because everything you need is exactly on the shelves. Just consider the technology of growing artificial rubies at home!
HOW TO GROW CRYSTALS RUBIES SYNTHETICALLY?
Growing ruby crystals can even become a home business option. After all, beautiful synthetic stones are already in great demand among buyers, so in the case of successful implementation of the project can bring you a good profit. Synthetically grown stones are used by jewelers, and are widely used in technology.
Ruby crystals can be grown according to the standard method, choosing the right salt. But it will not be as effective as in the case of salt or sugar, with a much longer duration is the growth process. And the quality will be questionable. After all, natural ruby on the Mohs hardness scale is second only to Diamond taking the honorable 9th place. Naturally, when it comes to business, in most cases, use another method developed more than 100 years ago in France.
You will need a special device, which has the name of the inventor of this method, ie Verneil apparatus. With it, you can grow ruby crystals, up to 20-30 carats in just a few hours.
Although the technology remains about the same. The aluminum dioxide salt with an admixture of chromium oxide is placed in an oxygen-hydrogen burner storage. Melt the mixture, watching as in fact “in the eyes of” grows ruby.
Depending on the composition of the salt you choose, you can adjust the color of the crystals, obtaining artificial emeralds, Topaz and completely transparent stones.
Working with the device will require your attention and some experience, but in the future you will be able to grow crystals that fascinate with their beauty, transparency and color play. In the future, such masterpieces are well served cutting and grinding, respectively, can be used for other purposes.
It is worth noting that artificially grown crystals are not precious stones, so even if you decide to do business on their cultivation, it does not require you to additional licensing.
The design of the device is simple, it can be easily done independently. But on the Internet already enough craftsmen offering drawings of the original installation, as well as its improved versions.
Set for growing ruby crystals at home
The principle of rubies production technology is quite simple and schematically shown in the figure below:
Scheme of the principle of operation of the apparatus Verneuil.
The funnel is filled with powder admixture of Al2O3 with admixture of Cr2O3.
Below the flame is fed oxygen-hydrogen burner.
The molten powder particles form layers of a growing ruby crystal.
The stand supporting the crystal gradually descends with the speed of ruby growth.
Understanding the principle of operation, any device does not seem so complicated. One of the sample drawings of the apparatus Vernale:
According to this technology, you can also grow and other expensive artificial stones, such as “Blue Topaz” , etc.
THE GROWING CRYSTALS OUT OF SALT AT HOME
The easiest and most affordable experiment you can do is to create beautiful salt crystals. To do this, you will need a few items:
Ordinary rock salt.
Water. It is important that the water itself contains as little as possible of its own salts, and better distilled.
The capacity in which the experience will be conducted (any Bank, glass, pan will do).
Pour warm water into the container (its temperature is about 50°C). Add kitchen salt to the water and stir. Once dissolved, add again. Repeat the procedure until the salt ceases to dissolve, settling to the bottom of the vessel. This suggests that the salt solution has become saturated, which we needed. It is important that during the preparation of the solution, its temperature remains constant, does not cool down, so we can create a more saturated solution.
The saturated solution is poured into a clean jar, separating from the sediment. Choose a separate crystal salt, and then put it in a container (can be hung on a string). The experiment was performed. In a few days you will be able to see how your crystal has grown in size.
GROWING SUGAR CRYSTALS AT HOME
The technology of producing sugar crystals is similar to the previous method. You can lower the cotton bundle into the solution, then the sugar crystals will grow on it. If the process of crystal growth has become slower, then the concentration of sugar in the solution has decreased. Add the sugar again, then the process will resume.
Note: if you add food coloring to the solution, the crystals will become colorful.
You can grow sugar crystals on sticks. To do this, you will need:
ready-made sugar syrup prepared similarly to salt saturated solution;
with a bit of sugar;
food dyes (if you want colored candies).
Everything is very simple. Wooden stick dipped in syrup and rolled in sugar. The more grains will stick to it, the better you get a result. Let the sticks to dry thoroughly, and then simply move on to the second phase.
Rich hot sugar syrup is poured into a glass, put the prepared stick there. If you are preparing colored crystals, then add food coloring to the hot syrup.
Make sure that the stick does not touch the walls and bottom, otherwise the result will be ugly. You can fix the stick with a piece of paper by putting it on top. The paper will also serve as a lid for the container, which will not allow any foreign particles to get into your solution.
In about a week you’ll get some lovely sugar lollipops. They can decorate any tea party, bringing to full delight not only children but also adults!
GROWING CRYSTALS FROM COPPER SULPHATE AT HOME
Crystals of copper sulphate obtained interesting shape, while having a rich blue color. It is worth remembering that copper sulfate is a chemically active compound, so the crystals from it should not taste, and when working with the material you need to be careful. For the same reason, in this case only distilled water is suitable. It is important that it is chemically neutral. Be careful and cautious when handling copper sulphate.
In this case, the cultivation of crystals from vitriol is actually the same as in previous cases.
Placing the main crystal for growing in the solution, you need to make sure that it does not come into contact with the walls of the dishes. And do not forget to monitor the saturation of the solution.
If you put your crystal at the bottom of the vessel, you should see that it does not touch other crystals. In this case, they will coalesce, and instead of one beautiful large sample you will have a mass of indistinct shape.
Good advice! You can independently adjust the size of the faces of your crystal. If you want some of them to grow slower, you can grease them with vaseline or fat. And for the safety of the sky-blue beauty can be treated with a transparent face varnish.
Interesting facts about gems!
There are 3 weight categories of diamonds:
Small. Weight of 0.29 carats
Average. Weight 0.3 to 0.99 carats
Large. Diamonds weighing more than 1 carat.
The popular auctions allow stones weighing from 6 carats. Stones with a mass of more than 25 carats are given their own names. For example: “Winston” diamond (62.05 carats) or “De Beers” (234.5 carats), etc.
