Because it is a typical Kansas winter day( grey, cold, and everything brown) I thought I would try a little more experimentation on this subject.
I bought a pillar candle at the thrift store and melted it down. I then added some essential oils to see what I come up with. The paraffin is cooling in ice cube trays now.
I think those darned thrift stores know that people just buy those used candles to melt down and reuse. It probably would have been cheaper to go buy paraffin.
