As you all know, I've been pouring, and testing, and testing, and pouring. I've noticed in my Illumination warmer, nothing last as long as I would like. I was wondering if it was just the warmer, so I pulled out some of my old formula's, they only lasted 1-2 hours! So I think that 8-12 with the new wax is FANTASTIC!!! I also got Sugar Cookie (MW) and Daystars Blackberry Jam Butter Cookie (I'm renaming Blackberry Flapjacks) to go for almost 18 in a regular bulb warmer. I'm working on pouring some other scents now, Amish Quilt & Warm Vanilla Nutmeg from AH/RE, Fall Festival from MW, NG's Apple Mango, and my Sunshine, we'll see how these do. I don't currently carry any Candle Warmers melters, with these results I probably won't. Just thought I'd update on my testing progress!!
