Glass vs. Fibreglass — What's the Difference?

Glass is a non-crystalline, often transparent amorphous solid, that has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the molten form; some glasses such as volcanic glass are naturally occurring.

Silica based glass extruded into fibers that possess a length at least 1000 times greater than their width.

A hard, brittle substance, typically transparent or translucent, made by fusing sand with soda and lime and cooling rapidly. It is used to make windows, drinking containers, and other articles

Ellipsis of fibreglass wool

A drinking container made from glass

A composite material made from fine fibres of spun glass held together with resin.

A lens, or an optical instrument containing a lens or lenses, in particular a monocle or a magnifying lens.

To apply fibreglass to.

A mirror

Same as fiberglass.

Cover or enclose with glass

A covering material made of glass fibers in resins

(especially in hunting) scan (one's surroundings) with binoculars

Hit (someone) in the face with a beer glass

Reflect as if in a mirror

Any of a large class of materials with highly variable mechanical and optical properties that solidify from the molten state without crystallization, are typically made by silicates fusing with boric oxide, aluminum oxide, or phosphorus pentoxide, are generally hard, brittle, and transparent or translucent, and are considered to be supercooled liquids rather than true solids.

A drinking vessel.

A mirror.

A barometer.

A window or windowpane.

The series of transparent plastic sheets that are secured vertically above the boards in many ice rinks.

Glasses A pair of lenses mounted in a light frame, used to correct faulty vision or protect the eyes.

To scan (a tract of land or forest, for example) with an optical instrument.

To become glassy.

To use an optical instrument, as in looking for game.

An amorphous solid, often transparent substance, usually made by melting silica sand with various additives (for most purposes, a mixture of soda, potash and lime is added).

Any amorphous solid (one without a regular crystal lattice).

(countable) A vessel from which one drinks, especially one made of glass, plastic, or similar translucent or semi-translucent material.

(metonymically) The quantity of liquid contained in such a vessel.

(uncountable) Glassware.

Lenses, considered collectively.

A pane of glass; a window (especially of a coach or similar vehicle).

(transitive) To fit with glass; to glaze.

(transitive) To enclose in glass.

(transitive) fibreglass To fit, cover, fill, or build, with fibreglass-reinforced resin composite (fiberglass).

To strike (someone), particularly in the face, with a drinking glass with the intent of causing injury.

To bombard an area with such intensity (nuclear bomb, fusion bomb, etc) as to melt the landscape into glass.

(transitive) To view through an optical instrument such as binoculars.

(transitive) To smooth or polish (leather, etc.), by rubbing it with a glass burnisher.

To reflect; to mirror.

(transitive) To make glassy.

(intransitive) To become glassy.

A hard, brittle, translucent, and commonly transparent substance, white or colored, having a conchoidal fracture, and made by fusing together sand or silica with lime, potash, soda, or lead oxide. It is used for window panes and mirrors, for articles of table and culinary use, for lenses, and various articles of ornament.

Any substance having a peculiar glassy appearance, and a conchoidal fracture, and usually produced by fusion.
