I grabbed a few at the dollar store to try out. At first I tried cd10 wicks, and they tunneled. Then cd12 and the flame was sky high with soot everywhere lol! Switched to wooden wicks that I know like the back of my hand, and it’s perfect! The mug isn’t even as hot as coffee after 4 hours burn time. Gonna power burn tomorrow and see what we get. Funny enough, I went to the thrift stores today just to look around. Mugs were $1.99 vs the $1 at Dollar General and Dollar Tree. And they were all really ugly lol! So I’ll definitely stick with new, and likely go the camping mug route. I happened to find these little espresso mugs, and thought they were adorable. They hold close to 2 oz of wax, which I thought was just too cute! I’m gonna burn it tomorrow and see how it does
