devitrification

Definitions

from Wiktionary, Creative Commons Attribution/Share-Alike License

  • n. The formation of small crystals in a glass as a result of slow cooling from the molten state

from the GNU version of the Collaborative International Dictionary of English

  • n. 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.

from The Century Dictionary and Cyclopedia

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

  • I've already tried encasing it in both Ink Blue and CIM's Crocus which not only takes away any devitrification concerns, but is also quite yummy.

  • 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.
