Borosilicate Glass
Discovered in Jena by Jenaer Glaswerk Schott & Genossen
HAS Ties to CARL ZEIS in Jena! Otto Schott (1851 - 1935) is generally credited, however, with the invention of borosilicate glass, however. His father was a glassmaker in Witten, Westphalia, Germany. Otto studied science in university and wrote a thesis on glass. In 1884, Otto joined Carl Zeiss and Ernst Abbe in founding the "Schott & Associates Glass Technology Laboratory", which has evolved today into the world-wide Schott company. Sometime between 1887 and 1893, modern refined borosilicate glass emerged from Schott's research, and his company introduced it commercially in the summer of 1893. The focus at first was on optical products. (Zeiss had specialized in products such as microscopes.) History of Carl Zeiss Stiftung History of Pyrex mention Carl Zeiss and Otto Schott as its creator

Back to Zeis and Jena again with this topic. Boron is most commonly used for the production of heat resistant glass.
Nearly all boron ore extracted from the Earth is destined for refinement into boric acid and sodium tetraborate. In the United States, 70% of the boron is used for the production of glass and ceramics. Borosilicate glass, which is typically 12%-15% B2O3, 80% SiO2, and 2% Al2O3, has a low coefficient of thermal expansion giving it a good resistance to thermal shock. Duran and Pyrex are two major brand names for this glass. Borosilicate Glass Wiki
