The use of oil lamps—simple vessels that use fuel sources such as olive oil to produce light—extends from prehistory to the present day, though they have been largely replaced by electric lighting and are now generally used for mood lighting or as an alternative to candles during power outages. The first oil lamps were made of naturally occurring objects, such as coconuts, shells, and stones. Later advances led to the production of clay and metal lamps.
