I meant how much is too little, sorry. Whenever I buy candles from a department store like Sears, or stores like Walgreens or even Wal*Mart there is always at least 1/2" of wax left over on the sides as the candle burns down. It's always been that way and I really didn't think anything of it. But then someone in my class mentioned hang up on the jars and the two ladies teaching the classes said that it is basically a personal choice when making candles. One said that some people want absolutely no hang up on the sides as well as no side effects (such as soot, smoke, etc.) and then others aren't so picky and are ok with a little hang up as long as there is no soot, no shrooms, no smoking and so on. Someone on here mentioned searching the threads and archives to get research and I have done that. I got a lot of answers I was looking for. But I just wanted to ask the current active posters how much you put up with? I have a 3 1/2" jar, and used a CD22 wick. I am 1 & 1/2 hours into my burn and all that is left on the sides is about 1/4" of wax maybe even just an 1/8th" not that much at all. Of course I realize I am not done with my test... I was just wondering.. What is the perfect candle?
