SINGLE-HANDLED Part of our Strata Dinnerware Collection, inspired by fluid forms Start the day with a big serving of something hot - this can hold 14 oz Durable glazed stoneware P.S. This product was previously called the Organic Mug Diameter = 4" D Capacity = 14 oz Material: Glazed stoneware Care Instruction: All our dinnerware is dishwasher, microwave, and oven safe up to 450 degrees. Avoid sudden changes in temperature - like putting a hot plate on a cold marble counter - as this can cause breakage. (Our Woven Trivet can be a good buffer here.) Remove minor scratches from cutlery and kitchen tools with Bar Keeper’s Friend - a classic standby scouring powder/magic potion. Works great with our Lurex Sponges, too.
