Very hot items placed directly on reconstituted (engineered) stone can cause cracks due to different thermal expansion rates. This damage caused by sudden and rapid surface temperature changes results in fractures in the stone.
We do not recommend that you ever put hot cookware directly on the surface of reconstituted stone. Therefore we advise that you always place very hot pots, pans and trays onto a wooden chopping board or heat trivet. It’s also suggested that electric fry pans and slow cookers are used on a wooden chopping board.
As a rule of thumb, natural stone can withstand more thermal expansion, therefore is more durable under heat pressure than reconstituted stone.
