Borosilicate glass is a type of glass known for its exceptional thermal resistance and durability. Made by adding boron oxide to the silica, it can withstand rapid temperature changes and high heat without breaking. This makes it ideal for laboratory equipment, kitchenware, and industrial applications. It’s also prized for its clarity and chemical resistance, which contributes to its versatility in various fields.

Schott B270 is a drawn crown glass that is a super-white highly transparent glass. It is suitable for a wide range of applications and comes in thicknesses from .9mm-10mm.

A first surface mirror is an excellent choice when clarity and optimal reflectivity are important to your application. Examples would be imaging, scanning, and 3D printers. Thicknesses range from 3-5.9mm

Corning 7980 is a high purity synthetic amorphous silicon dioxide manufactured by flame hydrolysis. Fused Silica is colorless and conbines a very low thermal coefficient of expansion with excellent optical properties that includes exceptional light transmission in the ultraviolet region. Corning uses inclusions and homogeneity to offer different grades of materials. Discovery can fabricate parts to your specifications from Corning 7980 material.

Fused Quartz, like fused silica, has a very low coefficient of expansion which makes it an excellent choice for conditioning plates for flat polishers, test flats, view port windows, and telescope mirrors. Discovery has thousands of pounds of fused quartz in stock from Tosoh Quartz, Momentive (GE), Heraeus among other quality quartz manufacturers. We have fabricated thousands of parts out of fused quartz and can provide sizes up to 72 inches in diameter x 12 inches thick.
