I appreciate your comments, Stella and you are almost 100% right! Where I live, we really don't have seasons....also - it's a very slight change in my formula and hardening process to adjust to any temperature/humidity change (humidity is not a problem here, either.). Yes, I've done my homework and I do burn my testers all the way down. So I'd have to disagree with you, and reassure you that I have perfected my soy container candle. Let me tell you, my research and playing with candles came YEARS before I poured my first candle. I still think if one is $2k in the hole with a soy candle, and still not achieving HT, maybe it's not for them.
