Hi starlessjade, I'm still a newbie too but have been testing for several months now and it is very frustrating. If I would have known then what I know now I would have saved a lot of money and time. Anyhoo, here is how I do it. First I see what manuf. recommends for the jar, then do a search and try to find posts for the jar, scent and wick that has worked for someone else (hard to find). If it's a new test candle, I will place just the wick in wax (as it hardens) so I can pull it out and replace w/ different size if needed. When I think I have it right, pour a new candle w/ wick anchored to jar this time and burn completely. I have a notebook that I write everything in for each candle. Bittercreek has a great candle test sheet I print out and use. They also have info for guidelines on what to look for when burning such as melt pool, flame size, etc. HTH.
