I've been trying to wick a 10 oz. apothecary using CB and patchouli. I have used everything from a 44-24-18z to my anchor rope. I have used singles and doubles to no avail...Here's the rub. They burn North and South but never reach East and West. Also, the melt pool is always over an inch deep no matter what wick I use...Is this normal for CB. I read somewhere that the depth should be 1/4-1/2" deep...... TIA, Brad
