Dishwasher safe using gentle and environmentally friendly detergents on the air dry cycle and do not overload the dishwasher. Hand washing is recommended when possible using a non-abrasive sponge. Avoid temperature shock by heating things slowly, evenly and carefully. Microwave safe, the temperature of the items may vary after microwave use. We recommend allowing items to cool before handling. Surface scratches may occur over prolonged use, to reduce handle with care and avoid contact with sharp objects.
