Hi all, Now my wife went and done it. She dragged me into candles too. We goofed around with a couple containers that went pretty well. She was happy. But now the guy side of me is kicking in and I have to know "why" why things do what they do. I've been reading alot and picking up quite abit. But these may still sound like candle 101 questions. So sit back and please don't laugh too much. She/we started with IGI4630A Harmony blend container wax. It was listed by the seller for its superior properties. I guess I can't really agree but here is what we did. We stated out with the double boiler method with a pyrex measuring cup and a meat therometer. We heated the wax to around 180, mixed in die and poured into a heated jar. The wet spots were minimal. We started with a CD-12 wix and a 3 1/2 jar and a 3 1/2 hex jar. We got a good melt pool, little to no wax hanging on the jar. But we got soot, and smoke and more soot. We experimented with longer wicks and down to about 1/8 inch. But still soot. To me this sounds like incomplete burning, even though we had a full melt pool. Is this accurate? We also tried a cd-10 and cd-8, but have the same results. Each time we used about the same amount of die. About 10 drops per lb. and cinnamon FO at about 1/2 oz. per lb. What effect does FO and liquid dyes have on burning. Do they aid in burning, or hinder? Also with all the soot and smoke, do wicks have different temperatures they burn at? And if so how do you determine the temp? Okay, now on to the Pillars. Each one is 3 inches. I bought some para/soy blend from a really nice lady that has a shop near my office. I poured two candles, both with lx-18 wicks she recommended. One was 3x3 with about 1/2 oz of FO per lb. and no dye. The second was a 3x6 with about 12 drops of red dye and no FO. The small candle burns really well, smells great but bulges badly. But during a long burn I do not get a blow out. Now the second candle is tunneling but the flame never gets more than about 1/4 of an inch tall, and is very weak. the tunnel is about 1 1/4- 1 1/2 in. in diameter but there is no bulging. I wish I knew what the blend is but it is 50/50 ish. I like the wax because its hideously long burning, doesn't smoke at all on the good burning candle and cheap. But does the dye hinder the burning as well? Also how can I control the bulging in a para/soy blend? Before the bulge happened I had a nice 1/4 - 3/8 wall and it was curling in nicely and getting consumed, but now the bulging is starting. I hope I didn't wear you out, but I think there are some good fundamental questions in there. I realize its all about testing. But I don't want to be shooting in the dark either. Thanks for all the help.
