1. Cutting: in order to get a better fire, the cut of moissanite is not eight hearts and eight arrows, but the best Belgian cut, also known as Belgian work.
2. Cleaning: first use hydrogen peroxide dilution cleaning, water temperature above 80 degrees, use pure water, the container is best to use glassware, soak for about 1 hour, then use anhydrous alcohol soaking 12 hours, ultrasonic pure water cleaning for half an hour, again use anhydrous alcohol cleaning, then using ultrasonic pure water cleaning.
3. Drying: blast drying oven at 120 degrees drying for two hours.
4. Sintering: atmosphere furnace vacuum to 0.08, filled with high purity argon to positive pressure, vacuum again to 0.08, again filled with argon.
Purpose of sintering: To improve the finish and brightness of the moissanite. When the electric atmosphere furnace is sintered to about 1300 degrees, some impurities will be refined out and the whole moissanite will become more translucent.
