My heat source is my stove, a water-filled pot with my pour pot inside. I'm using IGI pillar blend, 4625, 1lb. Just that, scent, and color. (1oz Orange Blossom, 1 dye chip) I know that I don't really think before posting. I just get a question in my head and ask, then later I think to myself, could I sound more ignorant? :rolleyes2
