The phlogiston theory is a supersedeit scienteefic theory that postulatit that a fire-lik element cried phlogiston is conteened within combustible bouks an released. A former theory of combustion in which all flammable objects were supposed to contain a substance called phlogiston, which was released when the object burned the existence of this hypothetical substance was proposed in 1669 by johann becher, who called it `combustible earth' (terra pinguis. The theory of phlogiston was predominantly german in origin, with much early work done in mainz, though it was widely believed through much of the eighteenth century -- two of the most prominent followers of the theory, johann joachim becher and georg ernst stahl (who first used the name phlogiston.
It basically said that flammable substances contained a fire like substance which was released into air when things burned they thought air had a finite capacity to absorb it, which was why things in an enclosed space would stop burning.

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. Similarly, in the late-eighteenth century, the oxygen theory was the best explanation of weight relations in chemical reactions while the conflicting phlogiston theory was the best explanation for why the properties of metals contrasted with the properties of the ores from which they were formed (kuhn 1977, 323. The theory of phlogiston recorded that phlogiston has negative mass, which is confirmed by experiments - negative weight of phlogiston leaves the metal and enters the air, resulting in a positive mass scale increases.
The phlogiston theory was before it waslearned that matter burns by using oxygen most chemists looked to explain combustion as the release of an unknown substance, which they named phlogiston.

Phlogiston theory prevailed as the dominant understanding of fire (and also, rust - which was thought of as a slower process of burning ie release of phlogiston) for at least a century, and it is not too difficult to see why.
