A "brazier" for burning aromatics (incense) is known as a censer or thurible. A thurible, a type of censer, is used to contain incense as it is burned. The priest blesses the incense saying the Prayer of the Censer. The censer is used to dispense incense. Incense is burned in this swinging metal container, or "censer". This is always done by burning granulated incense on a hot coal inside a censer. Some Orthodox Christians use a standing censer on their icon corner (home altar). There are also two prints of metalwork objects, a censer and crosier. The priest or deacon walks in front of the coffin with the censer. Eight red-robed "tiraboleiros" pull the ropes, producing increasingly large oscillations of the censer. Suspended below the elephant is a large quatrefoil-shaped censer that conceals speakers. The credentials written on yellow silk and other ceremonial silk was burnt in a censer. In Japan a similar censer called a is used by several Buddhist sects. In some traditions the censer with bells is normally used only by a bishop. A mid 9th-century copper-alloy hanging censer was discovered at North Elmham in 1786.
