Pressure-Rated Borosilicate Glass Discs
- Color: Clear
- Max. Temperature: See table
- Fabrication: See table
Commonly used as sight glass. Also called Pyrex and Schott glass, borosilicate glass resists clouding and pitting and is highly chemical and heat resistant. With a low rate of thermal expansion, it stays dimensionally stable during changes in temperature.
Tempered glass is stronger than annealed glass.
