Definition of glassy state
The glass state is not a state of matter, but its structure. Solid matter is divided into crystalline and amorphous. The atoms (or ions or molecules) that make up the crystal have a certain spatial structure (ie, the lattice). The crystal has a certain crystal shape and a fixed melting point, and does not have isotropy. The glassy state is an amorphous state. An amorphous state is a solid other than a crystal. It has no fixed shape and fixed melting point, and is isotropic. They gradually soften with increasing temperature before finally melting. After being softened, it can be processed into various shapes
