I sort of agree with Jane42. As far as burning tips go....BUT......As far as I can tell from your post FlameyJamie, you just started this adventure and are nowhere near having to worry about customers and what they want and what they expect. I have been doing this for a while, not years and years, but enough to know what I am doing. I do a lot of research of other people's candle. By that I mean I buy their candles and burn them, making notes and comparing them to my. You can buy the most expensive candle out there and you may still have the chance of mushrooming, or soot. There are candle makers who will not sell a candle if it does either. All in all... it comes down to personal preference. I think if you offer some information about how to keep these nasty things to a minimum, and offer tips on how to get the best burn, (along with picking the best Wax/FO/Wick combination for you) you have done your part. I have found that we are harder on ourselves about our candles than the general public is. Most people have seen mushrooms on candles they have bought before (Wal*Mart Mainstays candles always have them) . I have had some people say it's a reminder for them to trim the wick. I myself, try my best not to have them at all. But most important to me is the quality of the candle as a whole. Other Chandlers may accept shrooms as long as there is a great scent throw and wax consumption... again it all routes back to.... Personal Preference. Keep trying, you'll get to a candle recipe you are comfortable with.
