Miner’s Safety Lamp

Description (Brief)
The Joris Company made this safety lamp in Liege, Belgium during the 20th century. The measured markings along the lamp’s window indicate that this safety lamp was used to measure the amount of methane in the air, without igniting it. In the presence of methane, a blue "cap" would appear on the flame, with the height of the flame corresponding to the amount of methane in the air, easily measured by the markings built into the lamp.
