2. Safety lamp - Wikipedia

   en.wikipedia.org/wiki/Safety_lamp

   Both the Davy and Stephenson lamps were fragile. The gauze in the Davy lamp rusted in the damp air of a coal pit and became unsafe, while the glass in the Stephenson lamp was easily broken, and allowed the flame to ignite firedamp in the mine; later Stephenson designs also incorporated a gauze screen as a protection against glass breakage. [18]

3. Davy lamp - Wikipedia

   en.wikipedia.org/wiki/Davy_lamp

   The Davy lamp is a safety lamp used in flammable atmospheres, invented in 1815 by Sir Humphry Davy. [ 1 ] It consists of a wick lamp with the flame enclosed inside a mesh screen. It was created for use in coal mines, to reduce the danger of explosions due to the presence of methane and other flammable gases, called firedamp or minedamp.

   Gas mantle in a street lamp (cold) Mantles in their unused flat-packed form. To produce a mantle, cotton is woven or knit into a net bag, impregnated with soluble nitrates of the chosen metals, and then transported to its destination. The user installs the mantle and then burns it to remove the cotton bag and convert the metal nitrates to ...

   Geordie lamp. Stephenson's safety lamp shown with Davy's lamp on the left. The Geordie lamp was a safety lamp for use in flammable atmospheres, invented by George Stephenson in 1815 as a miner's lamp to prevent explosions due to firedamp in coal mines.

6. Humphry Davy - Wikipedia

   en.wikipedia.org/wiki/Humphry_Davy

   Rusting of the gauze quickly made the lamp unsafe, and the number of deaths from firedamp explosions rose yet further. There was some discussion as to whether Davy had discovered the principles behind his lamp without the help of the work of Smithson Tennant , but it was generally agreed that the work of the two men had been independent.

7. Firedamp - Wikipedia

   en.wikipedia.org/wiki/Firedamp

   Davy experimented with brass gauze, determining the maximum size of the gaps and the optimum wire thickness to prevent a flame passing through the gauze. [7] If a naked flame was thus enclosed totally by such a gauze, then methane could pass into the lamp and burn safely above the flame.
