Definitions

from The Century Dictionary.

  • noun Loss, either partial or entire, of the glassy or vitreous condition, or the process by which this result is attained.

from the GNU version of the Collaborative International Dictionary of English.

  • noun The act or process of devitrifying, or the state of being devitrified. Specifically, the conversion of molten glassy matter into a stony mass by slow cooling, the result being the formation of crystallites, microbites, etc., in the glassy base, which are then called devitrification products.

  • It might be imagined that the devitrification would disappear when the glass is heated to the fusing point; and so it does to a great extent, but for many operations one only requires to soften the glass, and the devitrification often persists up to this temperature.

  • The phenomena presented by devitrification, and by the formation of steel by cementation and casting -- the transition of the fibrous in the granular tissue of the iron, from the action of heat* and probably, also, by regular and long-continued concussions -- likewise throw a considerable degree of light on the geological process of metamorphism.

  • The process by which glass becomes partly crystallized as it cools (usually too slowly) from the molten state; also, the crystals formed by this process. Devitrification can also occur on the surface of glass after unsuccessful annealing or accidental heating to a high temperature.
