Cauldron Fire

You will need:
a cast-iron pot of any size
a lid that fits snugly, for putting out the fire
bricks, hotplate or other heat-resistant material to set the cauldron
on.
Epsom salts
rubbing alcohol
To keep the blaze going for 45 minutes in a five quart cauldron, you
need 1/2 gallon of Epsom salts and approximately 4 to 6 pints of
rubbing alcohol
Any cast-iron pot can be made into a cauldron with a fire of Epsom
salts and rubbing alcohol. This is a very safe blaze. Once the
cauldron is secured on a heat-proof surface, pour the Epsom salts in
until the bottom is covered, approximately 1 inch deep. Pour rubbing
alcohol over the salts until the alcohol is about an inch higher than
the salts. Hold a lighted match just above the alcohol. The liquid
will light and produce a strong orange flame. The flame burns cool,
unlike a wood fire, and it is difficult to burn things
in. When the flame gets low, cover to snuff out completely. Add more
rubbing alcohol to the cauldron and relight carefully. The warmer the
rubbing alcohol, the more quickly it ignites. This fire recipe leaves
a significant amount of sediment in the bottom of the cauldron. For
this reason, it is best to dedicate a pot strictly for cauldron use.
