What is spirt lamp?

A spirit lamp or alcohol burner is a small, portable stove that burns alcohol or other liquid fuel. It is often used in laboratories and workshops for heating, sterilizing, or performing chemical reactions. The flame is controlled by adjusting the wick's level, allowing the user to regulate the heat output. Spirit lamps can be made from various materials, including glass, metal, and ceramic, and often feature a screw-on cap to prevent evaporation of the fuel when not in use. They are considered safer to use than open flames as they are less likely to cause fires or explosions.
