Any container, often of bronze or pottery and fitted with a perforated lid, in which incense is burnt. The burning of incense as part of ritual life was a widespread practice in Mesoamerica, from as early as the Pre-Classic Period, as well as in Europe and the East. In Mesoamerica, there is considerable variety in form, from the simple small candelero (Teotihuacan) to the highly elaborate incensarios of Palenque and Mayapan. Copal, the Maya word for pine-resin, was widely traded as incense; it appears in the Aztec tribute lists in the Codex Mendoza. In China during the Han dynasty (206 BC-AD 220), a type of vessel known as a hill censer was used. Incense burners of the Ming dynasty (1368-1644) were made in two basic forms: a square vessel on four feet, fitted with two handles and a pierced lid, and a circular tripod vessel, also fitted with a perforated lid.
