What wicks I've decided on do what I want them to do with the candles that I sell ... basically consume the thing, release scent etc. everything to be a candle. Then I wanted that candle to be better. I occasionally experiment with wicks to see if I get a better throw or a longer burn or both and to see how the candle is burning. 1/4" rim on a 3x3 is too much leftover wax for me, but this is me. I am curious how you get 100 hours out of a 3x3.5 mold though, because I am able to get 60.5 hours out of that size of candle or is yours bigger? Both. Solidly since 2004 and on an off from 1994 to 2002. I didn't do squat in 2003. Paraffin is my preference and so are pillar candles. 1343 with the right amount of additives. It isn't broke, so I haven't bothered to try to fix anything though there have been some very challenging FOs. (Also a reason to test. You will find that one wick size does not burn all fragrances equally ... if you do, I will introduce you to Oil of Amber as Sliver pointed out, a patchouli and a few other heavier fragrances lol.)
