Most forms of glass have a maximum temperature of 500 degrees Celsius (932F). This maximum temperature is tipping point beyond which a glass item will melt and lose its structural integrity. Depending on what type of glass you have, it can have lower or higher maximum temperatures, but that is average value.

When looking at maximum temperature of glass, it is important to distinguish between glass types and their individual properties. Common types of glass and their maximum temperature ratings include:

Fused Silica Glass – This type of glass has an exceptionally high maximum temperature rating of 1,700C (3,092F). Fused silica glass is made from high purity silica and is used for applications that require a high level of temperature resistance.

Borosilicate Glass – This type of glass has a maximum temperature rating of 500C (932F) and is commonly used in laboratories and scientific settings. Borosilicate glass is made in traditional way and has very good thermal shock resistance, meaning it can withstand rapid changes in temperature without cracking or breaking.

Laminated Glass – Laminated glass has a maximum temperature rating of 400C (752F). This type of glass consists of two layers of glass bonded together using a special interlayer. The interlayer provides additional strength and durability, and can be used to create bullet-resistant or soundproof glass depending on its composition.

Tempered Glass – Tempered glass has a maximum temperature rating of 300C (572F). This type of glass is heat-treated to increase its strength and resilience. It is commonly used for car windshields and in other applications where strength and shatter resistance are paramount.

The maximum temperature of glass is an important factor to consider when selecting glass for a particular application. Knowing maximum temperature of each type of glass will help you identify one best suited for your needs.

It is also important to note that temperature rating of glass can be affected by other factors such as environment in which it is used, type of glaze used, etc. Therefore, it is wise to always keep an eye on temperature of your glass item and ensure that it is not exceeding its maximum temperature rating.

In summary, maximum temperature of glass can vary depending on type of glass you have. Generally speaking, highest rating is 1,700C (3,092F) for fused silica glass, and lowest is 300C (572F) for tempered glass. Understanding maximum temperature of each type of glass is important for selecting best material for your needs.
