Types of High Temperature Glassware
Tempered Glass
Tempered glass is a popular choice for applications requiring moderate heat resistance. It can withstand temperatures up to 470°F and is commonly used in fireplace doors and stovetop covers. The tempering process strengthens the glass, altering its breakage pattern to minimize injury risks. However, it is not suitable for environments with constant temperatures exceeding 500°F.
PyroCeram Glass
PyroCeram is a heat-resistant glass-ceramic known for its exceptional durability and high-temperature tolerance, reaching up to 1300°F. It is often used in commercial ovens and fireplaces due to its ability to withstand thermal shock. PyroCeram is also effective in blocking UV light, making it a versatile choice for both consumer and industrial applications. At www.onedayglass.com, you can find various custom sizes for your needs.
NeoCeram Glass
NeoCeram is a low-expansion glass-ceramic that can handle temperatures up to 1470°F. Its unique composition provides high resistance to thermal shock and mechanical stress, making it suitable for fireplace applications and hearth designs. With a smoother, texture-free surface, NeoCeram enhances aesthetic appeal while maintaining safety and functionality. More information can be found at www.fireglass.com.
Chemically Tempered Glass
Chemically tempered glass is created through a hardening process that enhances its strength without introducing internal stress. It can withstand temperatures up to 450°F and is often used for instrument windows and other optical applications. While it is not classified as safety glass, its increased durability makes it a practical choice for specific high-temperature environments.
Quartz Glass
Quartz glass offers the highest thermal resistance, capable of withstanding temperatures between 1700°F and 2200°F. Its low expansion properties make it ideal for scientific glassware and high-temperature applications. This type of glass is often utilized in laboratory settings where purity and durability are crucial. For various quartz glass options, visit axquartzstore.com.
VYCOR Glass
VYCOR glass is another high-performance option that can tolerate temperatures up to 2200°F. It is primarily used in coal burning stoves and environments requiring superior thermal resistance. Its clear design allows for optimal visibility while maintaining high safety standards.
