Debra, When you say, "it has a lot to do with temp.", could you please elaborate? Do you mean pouring temp. or the temp. at which you add the FO? I could use a few pointers. I heat the wax to about 175, then remove from heat and add fragrance oil, stir for 2 minutes, let sit until about 140 to 150 degrees, stir again, then pour. Maybe I am doing this wrong and that is why I don't always get a good scent throw. I'm using quality fragrance oils, usually at 1.5 oz. per pound. Thanks, Lisa
