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. Dick
