Are you wondering how exactly a candle smells like?
What creates the scent on or in your candle is the fragrance itself. Glass or container candles are only open at the top and therefore do not smell as strong as free-standing pillar candles. These freestanding candles have a more intense smell because the surface area to the air is larger than that of a glass or container candle. The larger the open area of a candle, the stronger the scent of the candle. It also depends on the amount of fragrance oil and also the wax. There are waxes that lock in the scent and do not release it as intensely as other waxes.
Have fun with your scented candles!
