Any cackling witch would be unrecognisable unless she was bent over her cauldron stirring her brewing potion! All witches want their symbolic cauldron in gunmetal grey or cast iron black in pride of place, even if they only use it for incense burning!
The cauldron symbolises Earth, Air, Fire and Water simply by the way it’s made in its cast iron and its 3 legs represent the three faces of women: maiden, mother and crone and the three phases of the moon: waxing, full and waning and the magickal Witch number of 3. It is the tool of magickal and spiritual transformation, so any negative issues can be written and burned at Samhain in your cauldron, helping this negative trait to be transformed. Even when you are using it, the metal is Earth, the Fire heats the Water inside and the steam it creates is Air…elemental magick indeed!!
Just remember that the cauldron is a personal tool and should never be used by another. Each witch must have her own magickal cauldron and bad luck will bestow anyone using someone else’s cauldron for magickal purposes!!
