@wthomas57 How strange, I noticed the opposite. For every 1lb of wax, I usually fill 2.67 of my 6 oz jars - that's with 1oz FO. The smaller one (which has roughly 4.2 oz of wax) I burn to test & keep for myself. When I used the Q210 I filled up almost three full jars as you can see in the picture I posted a bit ago. The one that is burned is almost full & I've never seen that happen. I don't fill my jars up to the very top because my cat will light her fur on fire trying to stay warm - which is why I don't make tins lol. Even though I don't fill them all the way up I am consistent in where I fill them to if that makes sense.
That was only one small pour so obviously it's not absolute, but I wanted to throw that out there. @Waxxy I did not notice a chemical smell or smoking, sorry! The only thing I can think of to check would be to make a non-scented candle, burn it, & see if you still smell chemicals?
