To vitrificate means to convert a substance into glass or a glass-like, non-crystalline solid, typically through the application of high temperature, rapid cooling, or specific chemical processes. This term is often used in materials science, ceramics, and metallurgy, where powders, clays, or metals are heated until they partially melt and form a hard, glossy, glassy phase upon cooling. In biology and cryopreservation, vitrificate can also describe the rapid cooling of cells or tissues into a glass-like state without forming ice crystals, helping to preserve structure and function. Overall, it denotes the process of achieving a glassy state.
