www.welshminerslamps.com/info_lamp_history.shtml states that In 1815 a guy by the name of Davy Humphry invents a Miner Safety Lamp for the usee of coal mines. He discovered a way that this lamp with many flammable gases can be around while in the coal mine. He placed a metal gauze around the flame in order to separate the heat from the flame to make the ignition temperature of methane be lower.
