Phlogiston vs caloric
Webb1 jan. 2005 · The term phlogiston is used in reference to a hypothetical material (called phlogiston), which was supposed to be at the origin of combustion in the 17 th and 18 th … 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.

Webb5 apr. 2024 · Quick Reference. 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: literally ‘fat earth’). WebbIn addition, the substantive counterpart to phlogiston in the new chemistry was not oxygen, but caloric. By focusing on the changing visions of chemical body across the revolutionary divide with a more sensitive probe into the historical actors’ material manipulations and linguistic usage, we can historicize their laboratory realities and philosophical agenda.
