Hi guys, just a quick question. I have been making candles for a few years, and I have saved my wax from year to year and reused it. Sometimes I would buy fresh wax to add to what I have saved. My question is, is there an additive I should use ro refresh my wax or is it ok to use over and over. I often thought of adding bees wax, but don't know enough about wax to do so. Can anyone advise me???
