Sapphire crystal glass 1. First, raw material processing and production processes will break down first clean crystal composition at 1200 ℃ high temperature.
2. After decomposition barrels flawless white crystal materials.
3. After 2050 ℃ continue firing desired crystal bar.
The uncut crystal block strip.
Crystal strip again subject to artificial selection, via the filtered crystal pieces, each piece is clean 5. After firing flawless.
6. After a piece of diamond-cut crystal pieces to be processed crystal glass.
7. After cutting, the grinder will then start to grind the surface at low speed, the work must be more than four times to reach the bright transparent mirror effect.
8. Finally, to the clean room and then through the optical processing, high temperature 280 ℃ of the mirror coating on both sides of special optical media.
