Magic_hands....don't feel alone...I'm in the gel club with you.

BUT...I can't always get my soap to gel and I can't figure out why. Actually, for my first 10 batches, I didn't seem to have a problem but the last 5 batches have been hit or miss. I have a wooden mold with a double-sided dam that comes with a fitted cover. That's all I've used for my 15 batches. Since I'm still testing, I usually divide my batch in half and scent and color each half differently and pour each half on either side of the dam so it's like I end up with 2 small batches. Well, here's what's perplexing, sometimes one side will gel and the other won't. My latest batch had the same coloring system on both sides but one side had a scent blend (BB's Lettuce FO, Tangerine EO and a touch of Neroli FO). And the other side had Kumquat. Both were scented at a rate of .7 PPO. The side with the blend gelled perfectly. After about 10 hours I decided to give extra insulation to the Kumquat side but the Kumquat side stayed semi-solid for 24 hours. I finally took the lid off because there was no zap and it's drying into a solid state now.
I'm not listing the recipe since it was the same on both sides, unless you want to hear it. If so, let me know.
Any ideas?
Thanks,
