[0002] Microcrystalline glass refers to a base glass with a specific composition with or without a nucleating agent. Under a certain temperature regime, it undergoes crystallization heat treatment, and a large number of tiny crystals are uniformly precipitated in the glass to form a dense polyphase composite of a microcrystalline phase and a glass phase. By controlling the type, quantity, size, etc. of the microcrystals, different styles of glass can be obtained.
