Ok, lets say that we have two candle makers with the same fragrance oil, same price point, etc. One uses 1 oz and one uses 1.5 oz. The candle takes the 1.5 oz. Everything else being the same, wouldn't the one that uses 1.5 be stronger? Also, I don't know where the .5 oz/lb came from either, but most people believe that to be true. Why?
