Marble is primarily composed of calcite, a form of calcium carbonate, which does not melt but rather decomposes when exposed to high temperatures. When heated beyond about 800°C (1472°F), calcite undergoes thermal decomposition, releasing carbon dioxide and transforming into lime (calcium oxide). This process makes it impossible to melt marble in the traditional sense, as it changes chemically rather than transitioning to a liquid state.
