If like most of us here you too thought diamonds were only found in mines, it sure is time for a revised thought then. Diamond could be found in labs. Yes, a team of Mexican scientists have worked out a way wherein heated vapor (from 40% alcohol, tequila blanco), deposits on silicon or stainless steel substrate form diamond films. These films wouldn’t work as real diamonds for Goldstriker’s next diamond encrusted gadget, however, they could make use as inexpensive electrical insulators.

Tequila was taken as the source for heated vapor given the ratio of hydrogen, oxygen, and carbon in it, which bears resemblance to the diamond extracting regions. The lab test have shown that heated liquid tequila and high temperature heating of gas results in solid diamond crystals which on dropping in silicon or stainless steel trays form thin uniform films of pure hard and heat resistant diamonds. This would give tequila makers an impetus to enhance their productions as there are plans of beginning industrial-scale applications sometime by 2011.
