An oil lamp is a device that uses oil as fuel to produce light. It typically consists of a container for the oil, a wick that draws the oil up, and a flame that burns the wick. Oil lamps have been used for thousands of years and were common before the invention of electric lighting. These lamps can be made from various materials, including glass, metal, and clay. They come in different designs and sizes, often used for both practical lighting and decorative purposes. The use of oil lamps continues in some cultures and settings, such as during religious ceremonies or outdoor activities.
