Cauldron Spirit

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. This is often done as part of a healing rituals,
invocations to the elemental spirit of Fire, scrying divinations,
Sabbat fire festivals, and various working rituals.

The sight of the cauldron blazing with flames can be very magickal
and mesmerizing, and when the alcohol has been steeped in aromatic
herbs, a sweet, but gentle, incenselike 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.
