Artificial marble countertop is made of a combination of polyester resin and marble dust. Although it is generally considered durable and resistant to scratches and stains, it is not heat-resistant. Therefore, placing hot pots or pans directly on an artificial marble countertop can cause thermal shock and result in cracks, discoloration, or other damage. It is recommended to use a trivet or hot pad to protect the surface of the countertop from heat damage.
