I know what you mean and I don't get it either. I'm very concerned about safety too. I have a tall, skinny 12oz Yankee container candle. In the beginning I trimmed the wick the usual 1/4" and it would reach a full melt pool pretty quick. After several burns I noticed the jar getting real hot and the flame too tall, would have to trim frequently. Now that the candle is in the lower portion of the jar I have to keep the wick trimmed to almost a nub in order to avoid a tall flame and an extremely hot jar. I don't like to have to do this and a lot of users wouldn't do this or even know that they need to do this.
I guess it just boils down to what you, as a candle maker, are comfortable with selling and having your name on. What really irks me are these people, so-called or self proclaimed "candle experts" and reviewers or whoever they are that don't actually know jack about what they are talking about. Some of them don't even possess the correct technical knowledge about candles to give a proper review yet they may talk trash about products that may actually be very good if used correctly. A lot of candle reviews and videos I have seen are disturbing, LOL.
