Using a 12 inch status jar, I have tried GW464, C3, CB advanced, CB135 and tried blending the soy waxes, but get no acceptable HT even after weeks of curing. I have tried echo8, CD 12,14,16 wicks. Grudgingly I decided maybe some paraffin blend would help with HT so used Accusoy#30 and it did help some but was major soot city even wicked down to Echo8. I really want to use soy but cannot sell candles with no HT. I would not want to buy them even tho they look perfect. Help!
