No, we have a strict no-fire policy for outside items for the safety of our kilns and other guests' pottery.We have this policy to protect our kilns and the other pieces of pottery in the kiln. For example, if an item is made of a material different than our bisque (or if the paint is a different type of paint than our paint), the item could explode, melt, or do something else that could damage our kiln and/or the other pieces in that kiln.
