These lamps have been produced from naturally occurring supplies akin to rocks, shells, horns and stones, have been filled with grease, and had a fiber wick. Lamps sometimes used animal or vegetable fat as fuel. Lots of of these lamps (hole labored stones) have been found in the Lascaux caves in fashionable-day France, relationship to about 15,000 years ago. Oily animals (birds and fish) have been also used as lamps after being threaded with a wick. Fireflies have been used as lighting sources. Candles and glass and pottery lamps have been also invented
