| The presence of glass 4 billion years old on the Moon indicates that water is crucial to the rate of devitrification. |
| Disideologization, devitrification, pluralization of the view of facts is occurring, Mircev comments. |
| No devitrification textures are noted in either the exogenic or terrestrial varieties. |
| High-viscosity silica gel produced by the hydration and devitrification of volcanic ashes can eventually concentrate in any open space, such as the cast of a limb. |
| The large range in U may be related to devitrification and alteration of the rhyolite groundmass. |
| We, also, attempted to illustrate the relationship between devitrification of the rigid amorphous fraction and crystallization kinetics. |
