Vitrify (verb) to convert into, or cause to resemble, glass or a glassy substance, by heat and fusion. Vitrify (verb) to become glass; to be converted into glass. Origin: [F. vitrifier; L. vitrum glass + -ficare to make. See Vitreous, -fy.]
Vitrification (from Latin vitreum, glass via French vitrifier) is the transformation of a substance into a glass, that is to say a non-crystalline amorphous solid. In the production of ceramics, vitrification is responsible for its impermeability to water. Vitrification is usually achieved by heating materials until they liquidize, then cooling the liquid, often rapidly, so that it passes through the glass transition to form a vitrified solid.
