A laboratory is a place where scientific experiments are carried out; it is full of the latest scientific equipment. Davy had samples of fire-damp sent from the mine to the laboratory in London, in sealed bottles.<\/p>\n<p>On 30 October 1815, he wrote to John Hodgson (who had written the description of the Felling Colliery Disaster) describing some ideas he had had for an invention called a safety lamp. A safety lamp is a kind of lantern that can be used in mines where fire-damp is present; it lights up the mine, so the miners can see, but crucially it does not allow an explosion to happen. Safety lamps were much safer for the miners to use than candles were.<\/p>\n<p>In December 1815, Davy came up with an even better safety lamp. Here is a picture of Davy\u2019s improved safety lamp:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-75 size-full\" src=\"http:\/\/wp.lancs.ac.uk\/lettersandthelamp\/files\/2017\/04\/03_davys_lamp.jpg\" alt=\"\" width=\"185\" height=\"540\" srcset=\"https:\/\/wp.lancs.ac.uk\/lettersandthelamp\/files\/2017\/04\/03_davys_lamp.jpg 185w, https:\/\/wp.lancs.ac.uk\/lettersandthelamp\/files\/2017\/04\/03_davys_lamp-103x300.jpg 103w\" sizes=\"auto, (max-width: 185px) 100vw, 185px\" \/><\/p>\n<p>On 9 January 1816, some of Davy\u2019s safety lamps were tested in the mine at Hebburn Colliery, in the north-east of England.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-85 size-full\" src=\"http:\/\/wp.lancs.ac.uk\/lettersandthelamp\/files\/2017\/04\/03_hebburn_in_british_isles.jpg\" alt=\"\" width=\"400\" height=\"600\" srcset=\"https:\/\/wp.lancs.ac.uk\/lettersandthelamp\/files\/2017\/04\/03_hebburn_in_british_isles.jpg 400w, https:\/\/wp.lancs.ac.uk\/lettersandthelamp\/files\/2017\/04\/03_hebburn_in_british_isles-200x300.jpg 200w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/p>\n<p>Some miners began to use Davy\u2019s safety lamp when they went down into the mine to hew (cut) coal.
