Hi there, I'm new to posting on these boards, but have been a lurker and gotten great tips. I've been making candles about 3 years, without a problem. Now, on to my dilemma.... I use a single pour blend (1275 from C&S), 60-44-18 paper core in my 16oz and LX-12 in the 8oz, and normally i use 1oz of scent to 1lb of wax...ok, now, these candles always burn well, full melt pool, no wax left, they smell great...Now, here's my problem, I received a new batch of wax (same kind, I just needed more), made the candles the same way I always do, and guess what?...They don't burn, well, they do for a little, but they leave alot of wax...some even outen themselves. I thought I was retarded:p , and made another batch with a ratio of 1/2 oz to 1lb, same results. Now, I know the logical answer is to get a bigger wick, but my question is.. Why all of the sudden are my candles not burning? These are the same scents, same wax, same jars, same wicks that I've used for 3 years. Any ideas? Thanks in advance for any help. I just wanted to let everyone know, that we took the candles and wax up to candle and supply to show them that something was wrong. They are figuring that yes, it was the wax. We were totally reimbursed for everything that we used/ruined because of the wax problem. I am extremely happy with the way that this was handled. There are always going to be problems, but if you stick with it, it'll probably get fixed. Have a great day!!
