Borosilicate Glass is the ideal type of glass for forming dab rigs and pipes. Silica components are used throughout the build which make this material extremely resistant to thermal shock. The German glassmaker, Otto Schott, invented borosilicate glass in Jena in the late 19th century. ⠀At the time, this borosilicate glass came to be known as Jena glass. Otto Schott was also known as the founder of today’s Schott AG. Otto Schott eventually sold borosilicate glass under the brand name DURAN.
The DURAN Group was founded as part of an equity carve-out in 2005 and Duran’s manufacture was transferred to it. After the introduction of Pyrex by Corning Glass Works in 1915, the name became synonymous with borosilicate glass in the English-speaking world (although a substantial portion of the glass manufactured for Pyrex is composed of soda lime glass starting from the 1940s. Borosilicate glass, however, is the name of a family of glasses with different types of glass that are suited for different purposes.
Borosilicate 3.3 glass such as Duran, NIPRO BSA 60 from International Cookware, and BSC 51 are the most common today. When producing borosilicate glass, the main ingredient is Boron as well as quartz, sodium carbonate, and aluminum oxide. A low expanding borosilicate glass, such as the above-mentioned laboratory glasses, is composed of about 80% silica, 13% boric oxide, 4% sodium oxide, and 3% aluminum oxide. Due to the high melting temperature needed, it is more difficult to make than conventional glass.
Through combining and melting boric oxide, silica sand, soda ash, and alumina, the outcome is borosilicate glass. It takes a significantly higher temperature to melt borosilicate glass, compared to regular silicate glass, hrndr some new techniques for industrial production have been needed. The manufacturing process relies fairly heavily on the geometry of the product and different methods such as floating, tube drawing, or moulding can be utilized.
Use of Term
Borosilicate Glass is just a fancy way to say this glass wont crack under heat change.
