Ceramic Glass: Ceramic glass is made from silica, boron oxide, alumina, and other materials. It's known for its high strength and thermal stability; ceramic glass can withstand temperatures up to 1000°C (1832°F). This makes it ideal for use in high-temperature environments such as fireplaces, kilns, and furnaces.
Ceramic glass is best for higher temperature applications. It can withstand constant temperatures up to either 1256 degrees F (PyroCeram®, 1/8″ or 3mm thick) or 1470 degrees F (NeoCeram®, 3/16″ or 5mm thick).
The most heat resistant forms tend to be borosilicate glass. This has a bunch of boron mixed in with the silica, which produces glass with much less thermal expansion. This reduces stress when the glass is heated and makes cracks less likely. Pyrex was one of the first borosilicate glasses.
Triple Glazing
If you want your windows to reduce heat even further than double-glazing, you can now get your hands on triple-glazed windows, which add a third layer of glass. According to Green Match, triple-glazed windows are around 60% more energy efficient than double.
Pyrex is a heat-resistant glass. The Corning Glass Works corporation invented Pyrex glass, which is a borosilicate glass. Pyrex also has a low alkali content, which helps it prevent corrosion.
Heat-resistant glass is a widely used glass type that is able to retain its shape in temperatures up to approximately 932°F (500°C) without breaking. Heat-resistant glass-ceramic materials are capable of withstanding temperatures up to approximately 1,800°F (1,000°C).
Glass. The most energy efficient type of glass for double and triple glazing is low emissivity (low-E) glass. Low-E glass has a microscopically thin coating of metal oxide on one of the internal glass surfaces. This coating reflects heat back into the home but still lets in the light from outside.
While low e glass could cost you more than any single or double glazed windows as it adds on to the microscopic extra layer of glass. You can hence expect to pay anywhere between $350 to $850 per window for the installation of a low e glass.
If the glass has an etched label in the corner that says “tempered” or “safety glass”, it has definitely been heat-treated.
While tempered glass offers enhanced strength, it has limitations in terms of adaptability after manufacturing. It cannot be cut or drilled, requiring precise pre-manufacturing measurements. Additionally, it can occasionally suffer from spontaneous breakage due to nickel sulfide inclusions.
Conversely, in hotter climates, thicker glass can help to keep heat out, reducing the need for air conditioning. The safety of glazing systems is also affected by the thickness of the glass. Thicker glass is generally stronger and more resistant to impacts, which can enhance the safety of the building.
Myth: Heat-resistant glass is expensive and inaccessible
Heat-resistant glass is available at a wide range of price points, depending on the specific type and application. While some high-end heat-resistant glass products can be costly, more affordable options are also available.

At What Temperature Does Glass "Break"? Glass bottles and jars are usually not affected by ambient, refrigeration, or warm temperatures. However, high heat (>300°F) and excessive thermal variations can cause glass to shatter or break.
1/4 to 3/8 inch thick "clear float" glass is commonly used to protect furniture - desk tops, dressers, nightstand, coffee tables, etc. The cost for this type of glass is typically more than $7 per square foot, with the most common customization being edge cuts which increases the price further.
Float glass is quite inexpensive but it cracks and breaks easily.
There are two types of glass made by the float process, clear glass and tinted glass. Most of the flat glass made by the float process is clear glass.
Double glazing consists of two panes of glass with an insulating gas layer, while triple glazing adds a third pane for extra insulation. Triple glazing provides better heat retention, reduces noise more effectively, and minimises cold spots, though it comes at a higher cost.
Low emissivity glass (often called 'low e glass')
Low emissivity glass can prevent the sun's heat from escaping a room.
K glass is super energy efficient. It uses a coating to let heat in from the outside while reflecting heat generated inside back into the home. This means it actually gains heat from the outside to help heat your home which can have a big impact on energy prices.
This change was justified by stating that soda–lime glass has higher mechanical strength than borosilicate—making it more resistant to physical damage when dropped, which is believed to be the most common cause of breakage in glass bakeware. The glass is also cheaper to produce and more environmentally friendly.
Tempered glass is preferable for passenger automobiles because its physical properties make it less likely to shatter into fragments when broken; it also cannot be cut or physically altered once hardened. In the Processes, Tempered glass is a physical function, whereas borosilicate glass is a chemical.
High thermal resistance: Borosilicate glass can withstand temperature changes without cracking, making it perfect for boiling water. Chemical stability: It is resistant to chemical corrosion, ensuring that it does not leach chemicals into the water when heated.
