Not meaning to change the original topic but since it's being brought up about pouring temps...I think I may have had a "lightbulb" moment in regards to my poor HT. I use IGI 6006 heat to 190, add dye and FO and pour at 180. As it has been mentioned, adding the FO drops the temp (sometimes significantly). I use the pour pot/double boiler method. After adding the dye and FO I keep my pour pot in the hot water and bring the temp back up to 187 or so and then remove from the hot water bath and cool to 180 and then pour into my containers. I'm only pouring about 3 containers at a time. After reading Stella's post it got me to thinking that this method may be causing my disappointing HT. I realize wicking has a hand in HT too but I think I have that part almost narrowed down. So I guess my question is...is my method hindering successful HT? Karen
