The burn test is going very well. I've been letting the candle burn for four hours per day. I let it cool and harden, and then trim the wick to 1/4 inch before relighting. At about four hours, I noticed the flame was a lot bigger, and because I want the candle to last long, the wick really needs to be trimmed to the 1/4 inch. I'm estimating the approximate burn time for this 16 oz. jar will be over 72 hours. Looking at Yankee burn times, I think this is good. The scent seems strong throughout the burn, but of course, I'll continue the test to make sure it will last all the way until the end. My candles are made of soy which is supposed to be better than the premium-grade paraffin that Yankee uses, and I make my candles in America too! Haha! Soy is supposed to be a better burn, and the candle has not smoked at all, except when blowing it out, but a clean burn throughout the four hours. If you are going to burn candles, soy is better than paraffin - beeswax is the best. I'm ready to make my first batch! I'll continue the burn test, and will do it again from the batch (since I'm new at this), but all has gone well, and I'm really pleased with this product. I think it is a quality candle just as good as Yankee at a much better price per oz. Yay! I always liked Yankee Candles, so I'm excited to make my very own! I'll give an update as I get to the end of testing.
