Rubies with their hands. Well, his head too. Bashny.Net

And now, dear readers, I will tell you how to cook a ruby ​​in his kitchen.
Although best in the country.
For the preparation we need ruby:
 - Aluminum powder;
 - Chromium oxide;
 - Oxygen;
 - Asbestos.
Asbestos sheet can be bought on the market. The furnace or the sauna pavilion. Aluminum powder - paint department. Paint-jewel. Only need to take the one that most confused. There's a packet of powder and organic basis, which we do not need a fuck. The hardest part - chromium oxide. But here you can wriggle out of. Famous paste GOI (the so green that some narrow-minded person called "HOE", although the GOI - an abbreviation of the State Optical Institute). So green it once again chromium oxide. You just have to burn it in a jar and what will - and will be chromium oxide.
Where to get the oxygen? Nothing easier. At the pharmacy. Oxygen bags are no longer sold, but there are "oxygen cocktail" which includes a small oxygen tank.
So. All the ingredients we have, you can start.





To begin mix chromium oxide with aluminum powder. Mix thoroughly. Value? From the stoichiometry 2Al + Cr2O3 = 2Cr + Al2O3. You can take a little more aluminum. Be beautiful.
We put the mixture on a sheet of asbestos, preparing the oxygen tank. Better to take the tube from the drip and not to approach the balloon itself to the place of preparation of the ruby. Of course, at the end of the PVC tube is necessary to implant a metal tip. Where can I get it? Well, get in the barn or in a landfill.
And so, everything is ready to stage 2 marlezonskogo ballet.
Stacked on top of the hill a few sulfur heads (with scrape off matches) and ignite. Starts spectacular reaction. (Keep your eyes and hands!) The temperature rises of more than 2000C, and we have to get oxygen hearth. Temperature reaches 2700S. Alumina formed during the reaction melts. Wait until all burned up and cooled down. The resulting slag is soluble in hydrochloric acid. (Where to? Well, think of something!) And filtered. In the filter, you will wait for small crystals of ruby. And so what you'll do with them ... Just do not try to sell. Though Ruby and artificial, but refers to the stones of the first category, and its turnover is strictly regulated.
