A Clay bowl is a tool primarily used to water and add soil to crops, as well as for compost and cooking, but has many other uses as shown below. It also can be used to bend letter stock, and Steel Spring. Placing on a Snow Bank makes Cold Bowl. It can be used to roll dice, and grow Bonsai.
Clay bowls can be stacked. In recipes where a bowl is used, an empty bowl is always returned eventually. The exception being a Daniell Cell Anode, where the bowl is consumed.
