A 5-inch (125 mm) square of wire gauze with ceramic center Using wire gauze with an alcohol burner. Wire gauze or wire mesh is a gauze woven of metal wire, or very fine, gauze-like wire netting. Wire gauze is placed on the support ring that is attached to the retort stand between a burner and glassware, or is placed on a tripod to support ...
A Bunsen burner placed atop a heatproof mat A heatproof mat An asbestos heatproof mat over a Teclu burner. A heatproof mat, also known as wire gauze or a gauze mat, is a piece of apparatus commonly used in tabletop lab experiments that involve moderate temperatures (for example, when a Bunsen burner is being used) to prevent damage to a work surface.

Chain-link fencing showing the diamond patterning A chain-link fence bordering a residential property. A chain-link fence (also referred to as wire netting, wire-mesh fence, chain-wire fence, cyclone fence, hurricane fence, or diamond-mesh fence) is a type of woven fence usually made from galvanized or linear low-density polyethylene-coated steel wire.
In film and theatre, gauze is often fashioned into a scrim. Gauze used in bookbinding is called mull, and is used in case binding to adhere the text block to the book cover. [19] The term wire gauze is used for woven metal sheets, for example placed on top of a Bunsen burner, or used in a safety lamp or a screen spark arrestor.
Davy used a fine wire gauze with a mesh of 784 holes per square inch (28 mesh). The required fineness of the mesh was scrutinised by the Miners' Lamp Committee in 1924, 109 years after Davy's work, and a recommendation to use a coarser mesh of 400 holes/sq in (20 mesh) of 27SWG wire was made. Lamps tested were as safe, and illumination ...
The current British Standard for metallic materials including wire is BS 6722:1986, which is a solely metric standard, superseding 3737:1964, which used the SWG system. The IEC 60228 , used in most parts of the world, defines standard wire sizes based on their cross-sectional areas as expressed in mm 2 . [ 3 ]
Structured packing is formed from corrugated sheets of perforated embossed metal, plastic, or wire gauze. The result is a very open honeycomb structure with inclined corrugations or flow channels, giving a relatively high surface area but with very low resistance to gas flow. The surface enhancements have been chosen to maximize liquid spreading.
Unlike wire gauze, which primarily supports glassware such as beakers, flasks, or evaporating dishes and provides indirect heat transfer to the glassware, the pipeclay triangle normally supports a crucible and allows the flame to heat the crucible directly. The triangular shape allows rounded crucibles of various sizes to rest in a stable way.
