Students really love to learn how to use molds because it can help to make a piece they are proud of. You will see in some of my later posts, some more unique ways of using molds. We teach hump and slump methods, and then we also use bowls, baking tins, etc using release like vaseline and a thin plastic wrap to easily remove their projects.
