Ive tested ginger peach, amish harvest, and banana nut breat. I havent had the air on while burning these, so Im not sure... I do have a VERY big house, but when I was pouring ginger peach the whole house smelled amazing. I can smell it if I put it in the half bathroom with the door shut. I guess I was just hoping for something more...Could it be that I burnt off most of the fragrance when pouring? Is 180 too hot to add fragrance? amish harvest and banana nut arent very strong either for some reason, but when I burn them in my electric oil burner, they are. Ill start using smaller jars to test in soon...
