Guitar slide made of borosilicate glass. Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.
The Quickfit brand is blown in Stone, Staffordshire, in the United Kingdom and marketed through DWK in the United Kingdom. 'Quickfit' has become a genericized trademark for all ground glass. Whilst the ownership and name of Quickfit has changed numerous times, all genuine Quickfit glass is stamped with a Q, displaying the brand name, the word ...
Schlenk flasks and Schlenk tubes, like most laboratory glassware, are made from borosilicate glass such as Pyrex. Schlenk flasks are round-bottomed, while Schlenk tubes are elongated. They may be purchased off-the-shelf from laboratory suppliers or made from round-bottom flasks or glass tubing by a skilled glassblower.

A stage in the manufacture of a Bristol blue glass ship's decanter.The blowpipe is being held in the glassblower's left hand. The glass is glowing yellow. As a novel glass forming technique created in the middle of the 1st century BC, glassblowing exploited a working property of glass that was previously unknown to glassworkers; inflation, which is the expansion of a molten blob of glass by ...
Glass may be blown, bent, cut, molded, or formed into many sizes and shapes. It is commonly used in chemistry , biology , and analytical laboratories . Many laboratories have training programs to demonstrate how glassware is used and to alert first–time users to the safety hazards involved with using glassware.
