Borosilicate glass was first developed by German glassmaker Otto Schott in the late 19th century.
Otto Schott is also founder of today's SCHOTT AG, which has sold borosilicate glass under the brand name DURAN since 1893.
Another manufacturer of DURAN is the DURAN Group.
After Corning Glass Works introduced Pyrex in 1915, the name became a synonym for borosilicate glass in the English-speaking world.
However, borosilicate glass is the name of a glass family with various members tailoring completely different purposes.
Most common today is borosilicate 3.3 glass like SCHOTT Duran and Pyrex by Corning.
