Since then, borosilicate glass and Pyrex have been used interchangeably in the English-speaking language. In 1915, Corning Glass Works brought it to the U.S. Invented in the late 1800s by German glassmaker Otto Schott, he introduced the world to borosilicate glass in 1893 under the brand name Duran. When Pyrex first hit the market in 1915, it was initially made from borosilicate glass. However, borosilicate glass is not the same as Pyrex. If you have a kitchen, you’ve probably heard of the brand name ‘Pyrex’ at least once. In terms of overall performance, borosilicate glass is far superior to regular glass. The boron in the glass makes it less soluble, preventing any unwanted materials from leaching into the glass, or the other way around. *Fun fact, borosilicate glass is so resistant to chemicals, that it is even used to store nuclear waste. This is why you can take borosilicate glass (and some bakeware like Pyrex-more on this below) out from the oven and run cold water over it without shattering the glass. In terms of temperature, the maximum thermal shock range (the difference in temperatures it can withstand) of borosilicate glass is 170☌, which is about 340° Fahrenheit. 69%), which makes it even less susceptible to fractures. Borosilicate glass has a much higher proportion of silicon dioxide in comparison to regular soda lime glass (80% vs. The coefficient of soda-lime glass is more than double that of borosilicate glass, meaning it expands more than twice as fast when exposed to heat and will break very quickly. It is relatively durable at only normal temperatures. This is where the name soda-lime glass comes from. It’s chemical composition is 69% silica (silicone dioxide), 15% soda (sodium oxide) and 9% lime (calcium oxide). Soda lime glass is susceptible to shock and does not handle extreme changes in heat. It accounts for 90% of manufactured glass worldwide and is used for items like furniture, vases, beverage glasses and windows. Many companies choose to use soda-lime glass for their glass products because it is less expensive and readily available. What’s the difference between borosilicate glass and soda-lime glass? For you, this means you can pour boiling hot water into borosilicate glass if you wanted to say, steep tea or coffee, without worrying about shattering or cracking the glass. Thanks to this, borosilicate glass has the ability to go straight from a freezer to an oven rack without cracking. This allows the glass to resist extreme changes in temperature and is measured by the “Coefficient of Thermal Expansion,” the rate at which the glass expands when it is exposed to heat. Take our high-grade borosilicate Kablo bottles for example.īorosilicate glass is made up of about 15% boron trioxide, which is that magical ingredient that completely changes the behavior of glass and makes it thermal shock resistant. What most people don't realize is that n ot all glass is created equally. Its durability has made it the glass of choice for high-end restaurants, laboratories and wineries. This means it will not crack under extreme temperature changes like regular glass. Borosilicate glass is a type of glass that contains boron trioxide which allows for a very low coefficient of thermal expansion.
