An alcohol lamp is a simple device used for heating and lighting, typically made of glass or metal. It contains a reservoir filled with a flammable liquid, usually ethanol or methanol, which is ignited using a wick. Alcohol lamps are commonly used in laboratories for experiments, as they provide a steady flame and are easy to control. These lamps are favored for their portability and safety compared to other heat sources. They are often used in educational settings, such as science classes, to demonstrate chemical reactions or for small-scale heating tasks. The flame produced by an alcohol lamp can be adjusted by raising or lowering the wick.
