COLOR ENHANCEMENT OF RUBIES BY HEAT TREATMENT

摘要

Natural rubies are heat treated , so if you did not at high temperatures over 500 in creating the causes of internal color going in a stable position of the engaged state and the lattice arrangement of the atoms which color can be improved. To prevent the reaction of the heat treatment process of the invention and the window processing of ore to facilitate the observation of the color change during heat treatment and heat-resistant material and to effectively remove the blue tones in both but when reducing the brightness and saturation of the color maintaining inclusions representing a natural the appropriate temperature for diffusion Act was invented .
