Well I thought I was on the right track with gb415. I poured several 2 1/2" mason jars a few weeks ago. I have been testing them this weekend. I poured 6oz wax with .6oz of FO. I am using C85 wick. The wick seems to be doing good, except for couple of them, the wick is producing black smoke around the 2 hour mark. If it doesn't give a full MP on the first burn, it catches up on the second. Problem is, the HT is not that great in most of them I have tried. I have the following FO that I have been testing. ~~ Lilac = scent throw is good ~~ Lavender = can't really smell anything except up close ~~ Love Spell = again, not much of a HT ~~ Cotton Candy = kind of ok ~~ Warm apple pie = good in my small bathroom Should I be upping the FO % ? Is it the wick? I tried a HTP 104 in one of them and it didn't work. ( that is the only htp I have) I am a little concern because I thought this was it and I ordered a case from candlescience. Any suggestions before its too late to cancel my order from CS...
