I also use soy and I have found the best hot (and cold throw) to be poured at 100-110. Some may say what? But the retention is wonderful when poured cooler. After cooled, I immediately seal them up (whether w/ a lid or in cello packaging), and I too, store them in my pantry for 2 days before testing. I've had great results...until I started getting cracks around my wicks the past couple of times! lol! But it's from a bad batch of wax. Good luck! I hope you have fun!
