What process is known as skull melt in gem synthesis?

The process known as skull melt refers specifically to a synthetic crystal growth method that involves the use of controlled cooling and temperature gradients to create high-quality synthetic gemstones. In this technique, a molten material is placed in a container, and the temperature is gradually lowered to allow for crystallization to occur. The term "skull melt" comes from the way in which the crystalline structure forms from the heated material, which can resemble a skull shape due to the method in which the furnace is designed.

The method is particularly effective as it creates fewer impurities and defects in the resulting crystals compared to other techniques, leading to gems with better clarity and overall quality. Mastery of this technique requires precise control over the temperature and environmental conditions, emphasizing its significance in the field of gemstone synthesis. Understanding this process is vital for recognizing the advancements in synthetic gemstone production and appreciating the quality of synthetic materials that can be achieved.
