Phlogiston: Burning down alchemy

The bridge between alchemy and chemistry was crossed when scientists tried to answer the question: “Why do things burn?”.

Starting from the perspective of four elements and arriving at the discovery of oxygen, this 100 year journey is a brilliant showcase of the difference between pseudoscience and science.

Learn about how this substance could help explain combustion and what hydrogen has to do with it.
