Hi Frank:
Do you have Richard Taylors booklet 'Beeswax Molding and Candle Making'?
Great little 38 page booklet. He writes about a home-made melter made from
a couple of 5-gallon cans. The lower can melts the wax. Above it is a can
with hot water that flows through spigot to the melted wax below. The
melter he says "refines the wax to the utmost purity". He also mentions
adding a few spoonfuls of vinegar to the water.
