Learn something new everyday. I'll bet that back when beeswax was the best candle material that the whiter the wax the better, the most valuable. I'm sure that the Church in the Middle Ages snapped that up. I, of course, think beeswax is still the best candle material - once in awhile I run into somebody who doesn't like the smell though. (What's wrong with them?! :-D)
