Also known as Pyrex and Schott glass, borosilicate sheets are heat resistant, clear, and have a super-smooth surface. They're used in a range of applications, from high-temperature viewports to 3D printing.

More durable than common glass found in window panes and drinkware, borosilicate resists expanding and contracting even under extreme temperature swings. It's why borosilicate is often used for exterior lighting and laboratory glassware—you can transfer it directly from freezer to oven rack without warping or cracking.

Borosilicate is optically clear—use it as a viewport or in optical and analytical equipment where clarity is key. It won't cloud or pit when exposed to most chemicals, such as acid, chlorine, bromine, iodine, and organic substances. In fact, borosilicate is so chemical resistant that it's used to store nuclear waste.

Because they're extremely flat and keep their shape at high temperatures, borosilicate sheets are used in 3D printing, where an accurate first print layer is critical to producing high-quality, geometrically accurate parts. Known in this context as build plates and print surfaces, they also prevent damage to the printer, which sometimes operates at extremely close distances. The flat, smooth surface makes them easy to clean. Sheets with chamfered edges don’t have sharp edges, so they won’t cut you as you reach in and retrieve prints or clean the print surface.
