While marble is heat resistant to some extent, it's generally not recommended to place hot pans directly on marble countertops for a long time.. Here's why:
Potential for Thermal Shock: Marble is a natural stone with a certain level of porosity. When exposed to sudden extreme temperature changes, such as placing a hot pan directly on a cool marble surface, the marble can experience thermal shock. This can lead to staining.
Risk of Staining or Discoloration: In addition to thermal shock, placing hot items directly on marble can also increase the risk of staining or discoloration. The heat can cause the marble to react with any spills or residues on the surface, leading to potential damage or marks.
To protect your marble countertops from heat damage, it's best to use trivets, hot pads, or heat-resistant mats to place hot pans and dishes on. These protective measures create a buffer between the hot item and the marble surface, reducing the risk of thermal shock and potential damage. Additionally, wiping up spills or splatters promptly can help prevent staining or discoloration over time.
