All of our pieces are food safe and oven safe. We recommend gentle hand washing or light dishwashing ensure the longevity of the piece. When storing your special item we recommend to avoid stacking if possible. For items where staking is most practical we suggest stacking between pieces of felt to limit any friction on gold edges. Our pieces are hand painted with real 22k gold, therefore they are not safe to use in a microwave. The porcelain we use is very dense and strong and our glaze is extremely scratch resistant so we hope you'll be able to enjoy your pieces for years to come. Thank you for shopping and enjoy your unique and special piece!
