How much temperature can the hearth marble withstand?

Marble is a series of calcium carbonate rocks and belongs to metamorphic rocks. It is not resistant to high temperature. When the temperature is higher than 350 degrees Celsius, it begins to change color, and when it is higher than 650 degrees Celsius, it begins to decompose into calcium oxide and carbon dioxide.

At present, high temperature resistant resins include modified silicone resin and siloxane resin; The temperature resistance of modified silicone resin is as high as 650 degrees Celsius.
