Shiny gas
The history of neon lamps goes back to 1675. This was the year in which French astronomer Jean Picard shook the world with the first Torricelli barometer. Upon his observance of the faint glowing of the barometer, he discovered mercurial phosphorescence. Thanks to tests and inventions, like the voltaic pile, the Geissler tube and the Ruhmkorff coil, emission of a blue or purple light from a glass tube became possible during the second half of the 19th century. The simultaneous discovery of noble gases like argon, helium, neon and xenon, as well as the spread of electrical energy, made possible the construction of neon lamps which in their book Neons. A Fleeting Ornament of Warsaw at Night, Jarosław Zieliński and Izabella Tarwacka call 'great grandneons'.
In the beginning, neons were produced for lighting. They were introduced for commercial purposes when electrodes were made sufficiently durable. The noble gases used for their production generated different colours: light blue for argon, light pink for helium, white for krypton, while xenon gave out a purplish-blue tint. In advertising, neons created compositions with luminous light-bulbs and illuminated signs, gradually taking centre stage.
In 1896, American electrical engineer and inventor Daniel MacFarlan Moore built a luminous tube which he used for experiments with nitrogen and carbon dioxide. Several versions later, some reached up to 61 metres in length. At the Electrical Exhibition of 1898, the "Moore Chapel," a small chapel mock-up illuminated by Moore’s tubes, at Madison Square Garden became the main attraction and brought the inventor to fame.
