Beautiful stone plate to keep food warm or cold. Due to its properties, soapstone is an excellent choice for a plate to keep food warm or cold. This material is heat-resistant, which means that you can place hot pans directly on it without the stone cracking or burning. Soapstone is also non-porous, which makes it stain-resistant and naturally antimicrobial1. These properties make it an easy-to-clean option for kitchen worktops and other surfaces on which food is prepared or served.
