The burn time on a single wick candle is 8-10 hours per candle ounce. In other words, a 10 ounce candle will burn for a minimum of 80 hours. For a three wick dough bowl, it’s 30 hours due to multiple wicks burning a set amount of wax. Five wick dough bowl candles burn for 40-50 hours. All of this, of course, is so long as the wicks are maintained to less than 1/4” at all times. The shorter the flame, the longer the burn time.
