A type of Davy lamp with apertures for gauging flame height. The lamp consists of a wick lamp with the flame enclosed inside a mesh screen.

If firedamp is drawn into the flame it will burn more brightly and if the proportions are correct may even detonate. The flame on reaching the gauze fails to pass through and so the mine atmosphere is not ...
It also led Sir Humphry Davy to devise another safety lamp, the Davy lamp, in which the flame was surrounded by iron gauze. The gauze had to have small spaces so that a flame could not pass through, but could admit methane, which then burned harmlessly inside the lamp.

This enabled the light to pass through and reduced the risk of explosion by stopping the "firedamp" methane gas coming in contact with the flame.
