Hi, sorry I didn't answer all the questions. I hit reply and thought I would be able to see what I was replying to, but couldn't. I just realized it is all below, I feel silly now. Anyway, I am using straight paraffin, with no additives (making container candles). I did try adding a teaspoon of a couple of additives that I got with my original kit. I am at work right now and I don't remember the name of them. I think it was poly AC something or other and kermicide. It is written on the bags. One is for candle smoothness and the other is for aid in mold release. It did not matter anyway, I got the same results. I am using 1 oz per pound of FO. I only melt 1 pound at a time.
