The size I used in the mottled 3" pillar was a 60048 - which it said was for a 31/2 to 4" but since the pillar was spicy scents - previously used 60 zinc, I decided to go with the larger. Think though the 1400 which is for a 21/2 - 3" would have been OK. Hate to waste another pillar though. I really like the way it burns. I use the htp in my containers but I do not use that in my pillars because of the slight bend at tip of wick, makes it sorta burn more on the side it bends toward. As far as getting the pillar out of mold, after leaving in the freezer for 10-15 minutes if it still doesn't come out I take wick pin out, put finger over hole in pillar and blow from bottom of mold, that always works for me. hth
