What does vitrifying mean?
Vitrifying means converting a substance into glass or a glass-like, vitreous material, normally through the application of intense heat. The process occurs in glassmaking, ceramics, and related materials science: silica may vitrify into glass, while a ceramic glaze can vitrify into a smooth, hard, often transparent surface. The verb can describe an active conversion, as in “the kiln vitrifies the glaze,” or an intransitive change, as in “the mixture vitrifies at a high temperature.” Vitrifying differs from merely melting because it specifically implies the development of a noncrystalline, glassy structure. Its associations with heat, transformation, hardness, and transparency make it a vivid term for both technical writing and descriptive prose, although it is uncommon outside specialized or literary contexts.
verbTo convert a substance into glass or a glass-like, vitreous material, especially by heating; to undergo such a conversion.
- The conversion of a substance into glass or a glass-like, vitreous state, especially through heating.
"As the kiln reaches its peak, the glaze begins vitrifying into a smooth, glass-like surface."
"The furnace is vitrifying the silica into a clear, glassy material."
"Under sustained heat, the ceramic coating vitrifies and forms a protective vitreous layer."
Vitrifying is the transformation that turns mineral-rich materials into something as hard and transparent as glass.

Etymology of vitrifying
Vitrifying is the present participle of the English verb vitrify, which comes through French from Latin vitrificare. The Latin verb combines vitrum, meaning “glass,” with facere, meaning “to make.” Words such as vitreous and vitric belong to the same Latin glass root, while vitrescent describes a tendency to become glass-like.
