Our ceramics are handcrafted in a durable, high-quality stone clay body and glazed with certified food safe. Every piece is dishwasher safe; however, hand-washing will always prolong the life cycle of your pottery. Dirt and stains on unglazed surfaces can be removed with a scrub brush and a bit of baking soda. Do not expose the wares to sudden, dramatic shifts in temperature (e.g. place into a hot oven from the freezer) or place over an open flame. We don’t recommend for Microwave & Oven.
