I'm sorry, I should of known to give more info! I'm using 100% soy wax No color, using mostly bakery scents from AH/RE. Butternut Pumpkin, Creamy Cinnamon & Vanilla, Apple & Pumpkin Strudel 1oz per pound. Struggles in the beginning of the 16oz reg mouth jar candles and never recovers from it. quite a bit of hang up even after 4 burns. The 8 oz seems to burn good with HTP 105 but not with the 1212. But I'm thinking the 1212 is to big for that jar..thank you all so much for your willingness to help me! Have a great morning!
