Hi, Thanks for the advice. Didn't quite understand the chart (I'm very new to this:undecided ) but I would have thought that double wicking a 4in wide container with 2 HTP 105s would have worked in getting the wax to melt edge to edge but it didn't. Being that I live in Japan, I can't just easily go out and get a whole bunch of wicks to try-NOBODY makes candles and there are no craft shops except perhaps in Tokyo. For anyone using ecosoya cb pure and who makes pretty large candles, which wick works best for you? Is there a wick that is so great that I wouldn't have to double wick a 3 or 4in wide container? Does anyone make candles in containers other than tin or glass? How does that work for you? Again, what wick works best for you? Thanks!! sofiajp
