Most people buy a scented candle for the fragrance. That is a reasonable place to start. But the fragrance is only one part of what makes a candle worth lighting again. A good scented candle does four things well. It burns evenly, producing a full melt pool without tunnelling. It throws scent into the room without being overpowering. It burns cleanly, without soot or an oversized flame. And it lasts — not just in hours, but in the quality of the burn from the first light to the last. When all four are working together, a candle stops being a product and starts being a presence.
