Many Witches pour a bit of ordinary surgical spirit [rubbing alcohol] into their cast-iron cauldrons and light it by carefully dropping in a lit match.
is often done as part of a healing ritual, invocations to the elemental spirit of Fire, scrying, divination, Sabbat fire festivals and various working rituals.
The sight of the cauldron blazing with flames can be very magical and mesmerizing, and when the alcohol has been steeped in aromatic herbs, a sweet but gentle, incense like fragrance is produced.
To make an herbal ~ Cauldron Spirit~, put into a glass bottle a small bunch of any of all of the following:
fresh lavender flowers and leaves, fresh mint leaves, fresh rosemary flowers and leaves, or fresh thyme flowers and leaves.
Fill the bottle to the top with the alcohol; cap it tightly, and then give it a good shake.
Keep it in a cool dry place for thirteen days, shaking it twice daily [every sunrise and every moonrise].
Strain through a double thickness of muslin into a clear bottle, cap tightly, and store away from heat or flame.
Cauldron Spirit will keep indefinitely.
