Fine mosque lamps are oil lamps that typically have a large round body and a narrower neck that flares towards the top.[1] They were often made with internal containers to be filled with oil and a wick to produce light.[1] They were usually made of enamelled glass, often with gilding. Some were also made in Islamic pottery, though this was much less efficient for actual lighting. These lamps were normally hung by a circular metal frame and suspended by chains that went through a number of loops on the outside of the body. The circular frames continue to be used in many mosques today, but with plain or frosted glass lamps for electric lighting.
