The regular form which a substance tends to assume in solidifying, through the inherent power of cohesive attraction. It is bounded by plane surfaces, symmetrically arranged, and each species of crystal has fixed axial ratios. See Crystallization.

The material of quartz, in crystallization transparent or nearly so, and either colorless or slightly tinged with gray, or the like; -- called also rock crystal. Ornamental vessels are made of it. Cf. Smoky quartz, Pebble; also Brazilian pebble, under Brazilian.

A species of glass, more perfect in its composition and manufacture than common glass, and often cut into ornamental forms. See Flint glass.

The glass over the dial of a watch case.

Consisting of, or like, crystal; clear; transparent; lucid; pellucid; crystalline.

Clear; transparent.

Clear; transparent.

Clear; transparent.

Transparent quartz; a body formed by a solidifying element or compound, having symmetrical plane surfaces; a glass of superior clearness; anything transparent and clear; the glass over a watch-dial.

Clear; transparent.

Anything congealed like ice with smooth surfaces; any natural body transparent or semi-transparent; a transparent substance made by fusing certain bodies together, as an alkali with flint or sand and lead; a fine kind of glass.

Consisting of crystal; clear; transparent.

One of the figures of symmetrical shape assumed by certain salts and other chemical compounds.

A superior kind of glass: (chem.) a piece of matter which has assumed a definite geometrical form, with plane faces.

Matter which has naturally assumed a geometrical from; pure quartz; fine glass.

Of or like crystal; clear; limpid.

The solid mathematical form assumed by many minerals.

Transparent quartz; flint glass; a watch-glass.

Consisting of crystal, or like crystal. Rock crystal, transparent or colourless quartz.

An inorganic body, which, by the operation of affinity, has assumed the form of a regular solid, terminated by a certain number of plane and smooth surfaces; glass of a superior composition and manufacture; anything clear as crystal.

A naturally-produced angular solid of definite form.

A substance occurring in a definite geometrical form which is essentially constant for that substance, and which the latter always assumes when the conditions for its production are present.

n. [Greek] A mineral body which, by the operation of affinity, has assumed a regular geometrical form a fine kind of glass; —any thing resembling crystal.

Crystals are hard, pellucid, and naturally colourless bodies, of regularly angular figures; Crystal is also used for a fictitious body cast in the glasshouses, called also crystal glass, which is carried to a degree of perfection beyond the common glass; Crystals, in chymistry, express salts or other matters shot or congealed in manner of crystal.

Consisting of crystal; bright, clear, transparent, lucid, pellucid.
