Craft glass refers to colored art glass used for frosting, emulsification, hot melting, patching, etc., after secondary artistic processing, used for engineering decoration, outdoor decoration, home decoration, etc，glasscookware. 
Sand molds for glass hot melt molds are aluminum silicate fiber paper and boards. The commonly used sand mold is to pave the pure quartz in the furnace. The sand layer is about 1.5cm thick, and then draw with bamboo sticks according to the design drawing. The details can be drawn with wooden chopsticks, so a concave shape is formed on the quartz sand. The pattern is used as a female mold, and release powder is sprinkled on it, and then the flat glass is placed flat on the female mold made of quartz sandpaper. When the glass is heated above a point, it will sink into the sand mold due to its own weight.
Process glass forming refers to the transformation of molten glass into a solid product with a fixed shape. Forming can only be carried out within a fixed temperature range. This is a cooling process. The glass first changes from a viscous liquid state to a plastic state, and then into a brittle solid state. Forming methods can be divided into two categories: artificial forming and mechanical forming.
