The cauldron is a symbol of the Goddess, and it's all about femininity. The cauldron is the womb in which life begins. Although it usually represents the element Water, the cauldron is an interesting tool because it can tie in to all four elements. You place it upon the Earth, heat it with Fire, fill it with Water, and send the steam up into the Air. In Celtic legend, the goddess Cerridwen possessed a cauldron of immortality and inspiration.
