Coal oil lamps are an ancient lighting tool that originated in the 19th century and became popular with the widespread use of kerosene. It mainly consists of a lamp holder, lampshade, wick, and oil storage tank. Lamp sockets are usually made of metal, sturdy and durable; The lampshade is made of glass material, transparent or semi transparent, which can gather light and prevent wind from extinguishing flames; The wick is the heart of a lamp, usually made of cotton thread or rope, soaked in kerosene, and emits stable light when ignited; The oil storage tank is used to store kerosene, ensuring the continuous combustion of the wick. The working principle is relatively simple, absorbing kerosene through a wick and igniting it to produce light and heat.
