Incense sticks, cones, and resin differ in shape, how they are heated, and the equipment they need. The best choice depends on the experience you want and how much setup you are comfortable with.
Stick incense is designed to smolder along its length. Some sticks have a supporting core, while others are formed without one. Use a holder suited to the stick's construction and size, with enough space to catch the ash.
Sticks are convenient when you want a simple lighting routine, but their strength and duration still vary by product. A longer stick does not automatically mean a better fragrance experience.
Cones smolder from the tip toward the wider base. Their output can change as they burn, and they need a burner designed for the heat at the base. Do not place a cone in an ordinary narrow stick holder.
Backflow cones and burners are a separate matched setup; an ordinary cone will not necessarily produce the same flowing-smoke effect.
Resin incense typically comes as pieces or granules that require a purpose-designed heating setup. Depending on the product, that may involve an appropriate electric burner or a charcoal system. Follow the directions for both the incense and the equipment; resin is not simply lit and left to burn like a stick.
For a first purchase, decide which holder or burner you are prepared to use before choosing the scent. All three formats benefit from careful placement and ventilation, and any burning or hot equipment needs attention.
