I was wondering when others test burn if they do a power burn on any of their candles. I dont sell my candles but I do gift them to family and friends. I got a couple of containers back from my son and boy were they a mess. It looks like they never trimmed the wick when they relite it or just let it burn for hours and hours. Lota of mushroom stuff they just let fall into the container. I think when we test burn we check it after 2, 3, and 4 hours and keep the wick trimmed. I dont think most people really do that, they just light it and let it go. Kay
