We worked with a U.S. maker of durable, restaurant-quality stoneware to create these equally robust mixing bowls, designed to withstand the rigors of the kitchen and move to the table with style. The bowls are kiln fired at extremely high temperatures for a fully vitrified, non-porous finish, then completed with a lead-free, glossy glaze in classic and timeless white. Intended to provide a lifetime of service, the superior construction allows for a two year warranty against chipping. The bowls nest for compact storage. Dishwasher safe.
