Soon after the introduction of the safety lamp underground, miners noticed that its flame changed if there were gases in the atmosphere. In the late-nineteenth century, lamp makers began to develop dedicated gas-testing lamps, such as the Clowes Hydrogen lamp, that would give more sensitive readings of methane levels.
