How'd they do that?? Pink
Lazurine Silicon Growing Silicon crystals from a single seed crystal is the most important part of the process. This takes place in a furnace which is heated to about 1,500 degrees Celsius (2,732 degrees Fahrenheit). In the furnace is a container filled with molten Silicon and a secondary element such as Phosphorus or Boron. The seed crystal is dipped into the molten material and is then withdrawn with a rotating motion, similar to making candles by dipping them in hot wax. Solidifying on the seed, the molten material takes on the same atomic structure as the seed. This molecular symmetry distinguishes a single crystal from unstructured or non-symmetrical material. Each finished crystal cylinder is approximately six inches in diameter and about four feet long. The cooled cylinders are then cut into chunks or, in the case of silicon chips used in many electronic devices, cut into wafers using a high speed diamond edge saw. The process for the Silicon specimens you see on the website stops here. However, in the case of creating Silicon chips for electronic devices, the process continues. It takes about 50 complex steps to convert the thin wafers into integrated circuits. The final step is cutting the wafer into hundreds of tiny circuit chips. **Author unknown** Aqua Aura Aqua Aura is quartz that is gold infused. The process takes 12 hours to both heat the quartz to 1600 Fahrenheit while setting a vacuum equal to 2 earth atmospheres and letting chemically purified gold (purer than 24 Kt bullion) vapors into the chamber when the temperature and vacuum are correct. This in turn bonds the gold to the lattice of the crystal forming a permanent bond that only strong acids or grinding can take off. Rainbow Aura is formed through the bonding of Gold and Titanium onto pure Quartz. Opal Aura uses Platinum in its bonding process with pure Quartz. Goldstone Goldstone is a glass with flecks of copper suspended within. The glass is made in a reducing furnace with copper salts added, which "smelts" the copper salts back to copper, which then crystallizes. Its discovery was probably originally an accident, from adding too much copper-bearing mineral to the melt, and having a reducing atmosphere at the same time. (Normally, the copper minerals in an oxidizing furnace would have been used to create a number of colors in the glass.) The copper platelets suspended in the glass give it its characteristic glitter. Other coloring agents added to the glass can change the basic copper colored variety to a number of other versions, such as blue and green etc. But the glass only is colored. The sparkles are still the same copper crystals.. Originating in Italy, it is still made
there by members of a single monastic community. The story goes that it
was for a long time a very closely guarded secret how they made it, and
even now manufacture of the material remains the primary source of income
for that monastery, though it's also made elsewhere these days. **Information supplied by The Marble Mansion** |
