All of our work is made with porcelain and is fired to roughly 2200 degrees fahrenheit. This means that all our work is microwave & dishwasher safe! Top rack is recommended when possible for the longevity of the glaze. Some items (such as pie dishes) are oven safe as well, but we do not recommend putting other items in the oven. Pottery can accommodate shifts in temperature, but does best when shifted slowly. We recommend that you refrain from taking items from the freezer/refrigerator and placing them directly into the microwave or oven. None of our pieces are safe for the stovetop.For cleaning, either proper dishwasher use or hand washing with soap with a non-abrasive brush/sponge will work well.
