Thanks for replies. Wow, so different climates can affect wicks as well? I have been doing lots of reading on c3 and lots of people say the cdn14 for my diameter jar, I have tried a cdn14 and it seems far too small, it is still quite cold in the uk at the moment so could could cold weather affect wick sizes? I'm not fussed at the moment about how my candles look, I just want to achieve a safe burning candle with great scent throw Thanks to mulberrysoap who kindly informed me that the coconut oil I have is 76 degree, candle is now made with the coconut oil added.
