Three Steps of Indirect-Heat Incense Burning: Preparing the Charcoal, Burying in Ash, Placing the Incense

Step One: Preparing the Charcoal

Choose a piece of charcoal made specifically for incense, light it, and let it burn through fully until the surface turns white. If the charcoal is not fully burned, the scent will carry a smoky, scorched note. Don't rush this step—better to wait a few extra minutes.

Step Two: Burying in Ash

Bury the fully burned charcoal in the incense ash, to a depth where "the ash surface is warm but not hot." The ash both retains heat and blocks the fire; its thickness and firmness determine how quickly the fragrance is released later. Beginners can practice with a fixed technique first, then gradually develop a feel for it.

Step Three: Placing the Incense

Directly above the charcoal, cover with a thin sheet of mica or metal foil, then place a small piece of agarwood on top. The residual heat slowly draws out the fragrance—no scorching, no burning—with clear distinction between the top, middle, and base notes. By rotating the angle of the thin sheet, you can also fine-tune the pace at which the fragrance is released.

Indirect-heat burning is not about speed; it is about the patience to let a single burner of incense speak slowly.

What Incense Material to Choose

For indirect-heat burning, thin slices or small fragments of agarwood are usually used; there is no need for large pieces of fine material. Choose material with a clean scent and natural oil distribution—qinan(kyara) has a livelier fragrance but is expensive, so ordinary agarwood slices are enough for beginners to practice with. Material that is too damp will produce white smoke, so drying it in the shade beforehand is more reliable.

Two Points for Beginners to Note

First, the environment should be quiet and free of wind—a breeze will scatter the fragrance; second, don't place too much incense at once—less but finer allows you to appreciate the layers. To learn systematically, offline incense culture(香学) classes offer dedicated hands-on sessions.
