Vitrification is the conversion of a material into a glass-like substance through the process of heating and cooling. Antonyms for vitrifies are words that represent the opposite meaning. They include: softens, melts, thaws, liquefies, unfreezes, defrosts, and deliquesces. These words indicate a transformation from a solid, glass-like substance into a liquid or soft state. Vitrification is used to preserve biological materials, such as embryos and tissues, and to produce ceramics and glass. In contrast, the antonyms of vitrifies often connote processes that are destructive or imply a loss of form or structure.
