Representative of the womb, the cauldron is still used in modern practice. While they were once used by witches and non-witches alike to cook over an open fire, there is no doubt that the symbolism of a cauldron is heavily associated with witches. The cauldron became associated with witchcraft mostly thanks to Shakespeare's 'Macbeth'. He portrays three witches around a burning cauldron who proceed to poison and curse the mixture. These characters were written when witch hunts had started to gain traction in England. Today, large cauldrons are rarely used to cook, even by witches. The most common uses for cauldrons in modern times is to hold or combine herbs, make simmer pots, or to have a safe place to burn something in a ritual.
