text: Wish I could help you. Am stumped as I used a CL12 in a 20cl glass using gingerbread at 10% FO and it literally has no HT at all. Very disappointed and despondant that these candles and ideas about what wick to use etc etc is very much a hit and miss affair. How on earth do you get to the point of selling when you spend most of your life attempting to test and wasting wax and glasses. Wasting a lot of money for very little return. Very despondant with the whole process, my 30cl is spot on though, but these smaller 20cl glasses, I may just give up using 20cl glasses altogether, seems they are just a waste of money.
