A spirit lamp is a small, portable device used for heating or lighting. It typically consists of a metal or glass container filled with a flammable liquid, such as alcohol or kerosene, and a wick that draws the liquid up to be ignited. Spirit lamps are commonly used in laboratories, kitchens, and for camping purposes due to their simplicity and effectiveness. These lamps are often used in educational settings for demonstrations in chemistry or physics. They provide a controlled flame, making them suitable for experiments that require precise heating. The design of a spirit lamp allows for easy refueling and maintenance, ensuring consistent performance.
