That depends on what you created with us!
Earthenware is not dishwasher or microwave safe, so if you picked something up off the shelf, grabbed some paint or glaze and did a fancy design, no, it's not microwave or dishwasher safe. It is still washable! Wash with running water rather than letting it soak in a sink of water.
Your etched glass is dishwasher safe.
Your vinyl on glasses and vases can technically go in the dishwasher, but we don't recommend it. Wash gently by hand, don't soak.
If you used acrylic paint (we didn't fire it in the kiln), it is not dishwasher or microwave safe, not food safe, and shouldn't be put in water or used for food or drink.
If you painted stoneware with us, you can microwave it, wash it, bake it, store food in the refrigerator, .... Isn't that awesome?!
