In the Orthodox Church, thurible is a metal censer suspended from chains, in which incense is burned during worship services. The practice is rooted in the earlier traditions of Judaism in the time of the Second Jewish Temple. The thurible consists of a censer section, four chains, and a metal ring around the chains used to lock the lid of the censer section in place. Burning charcoal is placed inside the metal censer, and incense is placed upon the charcoal, where it melts to produce a sweet-smelling smoke. This may be done several times during the service as the incense burns quite quickly. Once the incense has been placed on the charcoal, the thurible is then closed and used for censing.
