mushy tops but with almost a sugar crystal like consistency. I would have sworn it was something I did wrong but there was no rhyme or reason. Out of the same pour pot, same fo, same everything, 3 out of 10 candles would be ok. Those aren't good odds. Last night, I poured 3 candles, again, same pour pot, same fo, same wick, same jars.. NONE of the three candles hardened. They "slushed". I've never had this happen before and I've never seen or heard anything like it happening. This is the same technique we've used for years and have never had this happen. Something with this batch of wax tho, because I tried a bit that I had left over from our last batch and it was another beautiful candle.
