Vitrify is a process of glazing and hardening a material, usually glass or ceramic. GLAZE, in this context, is the application of a thin layer of material to the surface of an object, while hardening is the process of making something more solid and durable. The term vitrify is derived from the Latin word 'vitrum, ' which means glass. The process of vitrifying involves heating the material to a high temperature, which causes the molecules to fuse together and form a solid, glass-like material.
