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.
250ml DURAN® laboratory bottle. DURAN is a brand name for the internationally defined borosilicate glass 3.3 (DIN ISO 3585) produced by the German company DURAN Group GmbH since 2005 under license from the Schott AG, which was the first to develop it, and which sold it from 1893 until the equity carve-out of the DURAN Group in 2005.

There are several companies concentrating on the production of glass tubes made from special glass types. By using a special glass type with particular properties the glass tubes can be fit for a variety of applications. Some well-known manufacturers of glass tubes are: Four Stars Glass Tube Co., Ltd. Nipro Glass; Corning Pharmaceutical Glass ...
Vycor is the brand name of Corning's high-silica, high-temperature glass.It provides very high thermal shock resistance. Vycor is approximately 96% silica and 4% boron trioxide, but unlike pure fused silica, it can be readily manufactured in a variety of shapes.
Older clear-glass Pyrex manufactured by Corning, Arc International's Pyrex products, and Pyrex laboratory glassware are made of borosilicate glass. According to the National Institute of Standards and Technology , borosilicate Pyrex is composed of (as percentage of weight): 4.0% boron , 54.0% oxygen , 2.8% sodium , 1.1% aluminum , 37.7% silicon ...
The glass used for this purpose is either soda lime glass or borosilicate glass, and the metal, usually a type of stainless steel, is chosen for desired properties of strength. Borosilicate glass is superior to other formulations in terms of chemical corrosion resistance and temperature tolerance, as well as transparency. [6]
Glass-glass evacuated tubes are made with two borosilicate glass tubes fused together at one or both ends (similar a vacuum bottle or dewar flask). The absorber fin is placed inside the inner tube at atmospheric pressure. Glass-glass tubes have a very reliable seal, but the two layers of glass reduce the amount of sunlight that reaches the ...
