vitreo-, vitre-, vitr- +

(Latin: glass; glassy; like glass)

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.
vitrifiable, vitrifiability; vitrificable
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).

vitrified wheel
A grinding wheel whose abrasive surface is bound by glass or porcelain.
vitrified, vitrifying, vitrifies
1. To change or to make into glass or a glassy substance; especially, through heat fusion.
2. To become vitreous.
vitrified-clay pipe
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.
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.
vitrine: 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.

Vitrinite is a type of maceral, where "macerals" are organic components of coal analogous to the "minerals" of silicate rocks.

Vitrinite has a shiny appearance resembling glass. It is derived from the cell-wall material or woody tissue of the plants from which coal was formed. Chemically, it is composed of polymers, cellulose, and lignin.

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.

vitriol (s) (noun), vitriols (pl)
1. Any of certain metallic sulfates of glassy appearance: One kind of vitriol is copper sulfate, or blue vitriol.
2. An acid made from sulfur dioxide and very corrosive; mainly utilised in the chemical industry: Two examples of vitriols are ferrous sulfate or green vitriol and zinc sulfate or white vitriol.
3. Abusive or venomous language expressing fierce hate, anger, blame, or deep-seated ill will; subject to bitter verbal abuse. After years and years of living with a husband she didn’t love anymore, Jane expressed all the vitriol, resentment, and hostility that had accumulated in her for so long.
4. Etymology: from Latin vitreus "of glass, glassy", from vitrium, "glass".

Bitter or caustic feelings like the corrosive properties of vitriol.

Sarcasm that is verbally sharp or caustic.
