No. Phlogiston was a theory considered to be fact and actually hindered scientific knowledge until it was discredited. The theory was used to explain certain observations about flame, oxidation, and the formation of certain compounds, most noticeably cinnabar. As with some theories, phlogiston used variable factors to explain anomalies. For instance it was assumed to have negative weight under certain circumstances. Once oxidation was properly understood phlogiston theory was no longer considered true.

What is the phlogiston?
The alchemist and physician J. J. Becher proposed the phlogiston theoryThe phlogiston theory (from the Ancient Greek φλογιστόν phlogistón "burning up", from φλόξ phlóx "flame"), first stated in 1667 by Johann Joachim Becher, is an obsolete scientific theory that postulated the existence of a fire-like element called "phlogiston", which was contained within combustible bodies and released during combustion. The theory was an attempt to explain processes of burning such as combustion and the rusting of metals, which are now collectively known as oxidation.

Why does the scientific establishment sometimes reject new ideas?
because some scientific theories are not true for this advanced world. e.g. the early ideas about phlogiston.
Which is not a way to gain scientific knowledge?
a way not to gain scientific knowledge is by not using the right materials
What are scientific theories that proved to be wrong?
Some I know of: Phlogiston, Galileo's theory of tides, Greek proposition that all numbers are rational, Proposition that malaria is caused by airborne miasmas.
Is Phlogiston considered not to be scientific knowledge?
Phlogiston was an early scientific attempt to explain what is now referred to as the generation and flow of heat. It was believed to be a fluid that existed inside objects and could flow through them (even if they were solids)). It was replaced by the theory of thermodynamics.
What did scientist think phlogiston was?
Phlogiston can be defined as "a hypothetical substance once believed to be present in all combustible materials and to be released during burning." Chemistry was so underdeveloped at the time Antoine Lavoisier gained interest in it that it could hardly be called a science. The prevailing view of combustion was the Phlogiston Theory which involved a weightless or nearly weightless substance known as phlogiston. Metals and fire were considered to be rich in phlogiston and earth was considered phlogiston poor. The following were the main theories put forward for 'phlogiston': * Weight loss when combustibles are burned because they lose phlogiston * Fire burns out in an enclosed space because it saturates the air with phlogiston * Charcoal leaves very little residue when burned because it is made mostly of phlogiston * Animals die in an airtight space because the air becomes saturated with phlogiston * Some metal calxes turn to metals when heated with charcoal because the phlogiston from the charcoal restores the phlogiston in the metal
Is it possible to change a scientific theory?
yes. the Phlogiston theory of combustion is no longer considered correct. The same is true of the Geocentric theory of the Solar system, or of the Flat Earth theory.
Who propose the phlogiston theory?
The phlogiston theory was first proposed by Johann Joachim Becher in 1667. This theory is now considered obsolete and was replaced by the oxygen theory.
How many people believed in the phlogiston theory?
Most people in the scientific community accepted it in the 18th century.

Who rejected phlogiston theory?
Lavoiser rejected the phlogiston theory!

Is true about Scientific knowledge?
Scientific knowledge is not absolute.
What was the composition of priestley dephlogisticated air and Rutherford's phlogisticated air?
The facts, as they stand, are these: every creature, when respiring, releases phlogiston. In fact, respiration is simply to be considered a form of combustion. Anything that can burn contains phlogiston. Substances, when burnt, release this weightless, invisible substance - an element of their being, their composition - the phlogiston. The phlogiston is always in need of somewhere to go. Such as, air is best for the phlogiston. Air can absorb it. Taking this mode of thinking to its furthest logical conclusion we can only state that the reason creatures "suffocate" is because there is nowhere for the phlogiston to go. When air was removed from around a living creature then there is nowhere for the phlogiston to go and so respiration would cease and the creature dies.
What is the mixture of calx and phlogiston?
lead calx + phlogiston = metallic lead
How does disagreement scientist affect scientific knowledge?
