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.

Commonly used as sight glass.

Also called Pyrex and Schott glass, these glass tubes resist clouding and pitting and are highly chemical and heat resistant.

Able to withstand temperatures up to 2100° F, this quartz glass is useful in high-temperature applications that also require optical clarity, such as high-intensity lighting, fiber-optic production, and optical lens systems.

Blistering temperatures won’t melt these quartz tubes, and rapid temperature shifts won’t cause them to crack.
