My pottery can be washed in the dishwasher, although hand washing is always gentler on handcrafted ceramics because dishwashing chemicals may be harsh and fade glazes over time.
My pottery is high fired, therefore it should be fine in the microwave. However, because I am unable to test a variety of microwaves, I recommend avoiding using them in the microwave.
You can use my pottery in the oven, but always heat meals in ceramics from a cold oven. Avoid thermal shock by not exposing your pottery to fast temperature changes, as with all ceramics.
