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.
Brown glass jars with some clear lab glassware in the background Laboratory glassware may be made from several types of glass , each with different capabilities and used for different purposes. Borosilicate glass is a type of transparent glass that is composed of boron oxide and silica, its main feature is a low coefficient of thermal expansion ...
In 1908, Eugene Sullivan, director of research at Corning Glass Works, developed Nonex, a borosilicate low-expansion glass, to reduce breakage in shock-resistant lantern globes and battery jars. Sullivan had learned about Schott's borosilicate glass as a doctoral student in Leipzig, Germany. Jesse Littleton of Corning discovered the cooking ...
Container glass is a type of glass for the production of glass containers, such as bottles, jars, drinkware, and bowls. Container glass stands in contrast to flat glass (used for windows , glass doors, transparent walls, windshields ) and glass fiber (used for thermal insulation , in fiberglass composites, and optical communication ).
A Pyrex borosilicate glass measuring cup. Borosilicate glasses (e.g. Pyrex, Duran) typically contain 5–13% boron trioxide (B 2 O 3). [75] Borosilicate glasses have fairly low coefficients of thermal expansion (7740 Pyrex CTE is 3.25 × 10 −6 /°C [78] as compared to about 9 × 10 −6 /°C for a typical soda–lime glass [79]).
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.
