I tend to do the same thing as you when I test. Once I've got the initial wicking right (1 hour for every inch....) I like to give my candles the power burn test. I pretty much light the sucker up, and leave it burning so that I can observe what happens. You are correct - there are some people that will do that, and you have to make sure of what your candle will do in that situation..... I'm one of those people that likes to have candles burning continuously. Very often I will light a candle at 10:00am in the morning, and not extinguish it permanently until I go to bed at night, around 10:00pm! I will trim the wick during the day, but for the most part, it stays lit. Now, I have not had a lot of success getting mottles to do that - they start to bulge out after a few hours. Rustics on the other hand, have shown great promise.........
