What does vitrify mean?
Vitrify means to convert something into glass or a glass-like material, usually through the application of intense heat. The word is especially associated with ceramics: when a clay body or glaze is fired, vitrification can produce a dense, vitreous, nonporous phase that gives the finished material strength and distinct surface qualities. The process can also be used more broadly for materials that become amorphous or glassy when heated. Vitrify may be used transitively, as when a scientist says that heat will “vitrify the mixture,” or intransitively, as when a ceramic “vitrifies” in the kiln. Although its literal meaning is highly technical, the verb is sometimes used figuratively for a person or situation becoming emotionally hardened or fixed. Its vocabulary value lies in connecting ordinary language about glass with specialized processes in pottery, manufacturing, conservation, and materials science.
verbTo convert a material into glass or a glass-like substance, especially by heating, or to become glassy or amorphous. The process is especially important in ceramics, where vitrification produces a dense, nonporous glassy phase.
- To convert a material into glass or a glass-like substance by heating.
- To become glassy, vitreous, or amorphous, especially during the firing of ceramics.
"At high temperatures, the mixture vitrifies into a smooth, glass-like material."
"The silica-rich coating vitrified during firing and sealed the surface."
"As the glaze was heated, it began to vitrify, producing a smooth glassy finish."
Some of the world's most durable ceramics depend on a dramatic transformation: when heated, they vitrify into a glassy, nonporous structure.

Where does vitrify come from?
Vitrify comes from French vitrifier, formed from Latin vitrificare, meaning “to make into glass.” The Latin verb draws on vitrum, “glass,” which is also the source of related English words such as vitreous and vitric. The development reflects the close association between heat, glass formation, and the transformation of materials into a vitreous state.

How vitrify is actually used
Vitrify is primarily formal and technical. It is common in ceramics, materials science, geology, and discussions of heat-resistant or vitrified materials; in everyday speech, it is usually used metaphorically for becoming rigid, fixed, or emotionally frozen.
