vitreo-, vitre-, vitr- +

1. The act, art, or process of vitrifying; also, the state of being vitrified.
2. The act, process or operation of converting into glass by heat; as the vitrifaction of sand, flint and pebbles with alkaline salts.

1. The manufacture of glass and glassware.
2. Glass blowing or glassblowing.

Capable of being converted into glass by heat and fusion.

Flint and alkaline salts are vitrifiable.

A reference to a process in which a glassy or noncrystalline material is formed by fusion under conditions of intense heat.

To convert into glass; to vitrify.

1. The process of converting materials into glass or a glass-like amorphous solid which does not have any crystalline structure.
2. In pottery, the point at which a pot loses its porosity during a firing.
3. The progressive fusion of a material during the firing process; as it proceeds, glassy bonding increases and the porosity of the fired product decreases.
4. A forming of a supercooled liquid; such as, glass.
5. The act or process of vitrifying; a state of being vitrified.

When the starting material is solid, vitrification usually involves heating the substances to very high temperatures. Many ceramics are produced in such a manner.

Vitrification also occurs naturally when lightning strikes sand, where the extreme and immediate heat can create hollow, branching rootlike structures of glass, called fulgurites (natural hollow carrot-shaped glass tubes formed in quartzose sand or soil by lightning strikes).

1. To change or to make into glass or a glassy substance; especially, through heat fusion.
2. To become vitreous.

A pipe, made of clay treated in a kiln to induce vitrification, with the surface glazed to keep water from seeping through the pipe surface; used for drainage.

A grinding wheel whose abrasive surface is bound by glass or porcelain.

1. Having the form or appearance of glass.
2. Resembling glass; glasslike.

1. To convert or change into glass or something like glass.
2. To change or make into glass or a glassy substance; especially, through heat fusion.
3. To make or to become vitreous.

1. A translucent material resembling glass.
2. A genus of terrestrial gastropods, having transparent, very thin, and delicate shells; similar to appearance of glass.

1. A glass-paneled cabinet or case for displaying articles; such as, china, objects d'art, or fine merchandise.
3. A cabinet or case with glass walls for displaying specimens or art objects.
2. Like glass.

1. One of the primary components of coals and most sedimentary kerogens. 2. A type of woody kerogen* that is relatively uniform in composition.

Since vitrinite changes predictably and consistently upon heating, its reflectance is a useful measurement of source rock maturity.

Because vitrinite originated in wood, its occurrence in marine rocks may be limited by the depositional processes that act in a given depositional environment.

*Kerogen is the naturally occurring, solid, insoluble organic matter that occurs in source rocks and can yield oil upon heating. Typical organic constituents of kerogen are algae and woody plant material.

1. Any of certain metallic sulfates of glassy appearance, as copper sulfate or blue vitriol, iron sulfate or green vitriol, zinc sulfate or white vitriol, etc.
2. Oil of vitriol; sulfuric acid.
3. A highly corrosive acid made from sulfur dioxide; widely used in the chemical industry.
4. Abusive or venomous language used to express blame or censure or bitter deep-seated ill will; subject to bitter verbal abuse.
5. Something highly caustic or severe in effect; such as, criticism.
6. Fierce hate and anger expressed through severe criticism.
7. To expose to the effects of vitriol or to injure with vitriol.
8. Etymology: from about 1386, "sulphate of iron", from Old French vitriol (13th century), from Middle Latin vitriolum, "vitriol", from neuter of vitriolus, from Late Latin vitreolus "of glass", from Latin vitreus "of glass, glassy", from vitrium, "glass".

So called from its glassy appearance in certain aspects. Meaning "bitter or caustic feelings" first attested in 1769, with an allusion to the corrosive properties of vitriol.
