Once considered an important tool of ritual magick, a thurible is a covered incense burner, or censer. It is generally made to be hung, or carried on the end of chains. Although it has fallen out of use in many traditions with the advent of self-igniting incense, thuribles are still used in Catholic and Eastern Orthodox Churches. Burning charcoal is placed inside the metal censer. Incense, sometimes of many different varieties, is placed upon the charcoal.
