The process of the glassy substance from the molten state to the solid-state is gradual, and the changes in physical and chemical properties are also continuous and gradual. This is markedly different from the crystallization process of the melt, and a new phase is inevitably present in the crystallization process, and many properties are mutated near the crystallization temperature point. The glassy substance is completed from a molten state to a solid-state in a wide temperature range. As the temperature gradually decreases, the viscosity of the glass melt gradually increases, and finally, solid glass is formed, but no new phase is formed in the process. On the contrary, the process of heating the glass into a melt is also gradual.
