So I tried a zinc wick 60-44-18, a 27 flat braid wick and then a 24 flat braid wick. I know I should be wicking for the center of the candle on this one, so here are the results:
Zinc wick burned wildly at first with a very high flame, calmed down towards the middle of the burn, then seemed to do "fair" for the rest of the burn.
27 flat braid, wick too big, burned too wildly again, had a blow out...then calmed down "some" towards the center to the bottom
24 flat braid wick burned wild at first, then had a major blow out, then calmed down, but the flame was much too high.
So, I'll now order the 21 flat braid and see what happens next. Has anyone wicked these pyramid candles successfully? If the 21 flat braid is still too wild, which would you suggest I try next? I really want this candle to work, I know my customers will love it.
