Soy Wax Candle Forum - Online resource for soy candle makers

Does anyone know a wick that can be used with the flake 415 soy wax in a 16 oz apothecary jar? I really just want to use 1 wick, but am currectly having to use 2 of the 1400 hemp/cotton wicks. I think this is too hot but my partner seems to think it's ok. I'd like to see a longer burn ratio for this style of candle we offer. Any suggestions?
