WebbThe phlogiston theory was discredited by Antoine Lavoisier between 1770 and 1790. He studied the gain or loss of weight when tin, lead, phosphorus, and sulfur underwent reactions of oxidation or reduction (deoxidation); and he showed that the newly discovered element oxygen was always involved.

Webbconception, as phlogiston had some detailed links with observed phenomena and with very concrete practical operations. And Lavoisier’s theory relied es-sentially on caloric, the … Phlogiston theory states that phlogisticated substances contain phlogiston and that they dephlogisticate when burned, releasing stored phlogiston which is absorbed by the air. Growing plants then absorb this phlogiston, which is why air does not spontaneously combust and also why plant matter burns as well as it does. Thus phlogiston accounted for combustion via a process that was the inverse of that of the oxyg…
