Phlogiston

 

the hypothetical principle of combustion in the view of 18th-century chemists. According to the phlogiston theory, proposed by G. E. Stahl, all flammable materials, such as wood and oils, and non-noble metals, such as copper, iron, lead, and tin, are composed of ash and phlogiston, which is released on burning or roasting. Despite its erroneousness, the phlogiston theory played a major role in the establishment of chemistry as a science; it was the first “to generalize many reactions (of oxidation), and this was already a very important step in science” (D. I. Mendeleev, Izbrannye lektsii po khimii, 1968, p. 60). The phlogiston theory was refuted by A. Lavoisier at the end of the 18th century.
