In China, the use of natural aromatic ingredients has a long history. Even during the Xia Dynasty, there were ceramic incense burners used as daily necessities. Compared to many foreign practices that involve using essential oils extracted from natural aromatic ingredients, China has a preference for directly burning these materials. In the practice of Chinese incense culture, burning natural aromatic ingredients is the primary form of incense offering. These ingredients are either directly placed in incense burners or processed into slices, powders, coils, sticks, or cones for burning.
