Robert Boyle
Robert was an alchemist who was interested in Henning's work with phosphorus that he created his own experiments with phosphorus and put together sulfur in a piece of paper with half a gram of Toluca which was the precursor of the match having fire on demand. -
Period: to
Brandt's Hennig
He believed that there was gold in the body but instead studied urine. He distilled the urine to separate the unimportant parts of it to create a paste, then heated it to make phosphorus. -
Period: to
Johann Becker
He believed that fire was caused by an eternal entity named Phlogiston. They thought it was an odorless, colorless, tasteless, and weightless substance that caused things to burn to reduce them back to their true form. -
Period: to
Henry Cavendish
Cavendish experimented with many metals, and in one experiment, he added zinc to acid and started to see a reaction with the zinc having bubbles and started to collect the air being produced. It didn't smell, see, or taste anything, and then he added a flame. He didn't know that he had created a new element called hydrogen. -
Period: to
Joseph Priestley
Priestley was fascinated with the fixed air that he mixed with water and accidentally created the first fizzy drink, he was also the one By adding mercury calx mercuric oxide to a test tube and then adding mercury which would trap the gas. Add the whole test tube to a mercury bath and begin heating the powder in the tube began to see a reaction and discovered oxygen, but he instead called it dfleege istic eight sit air. -
Period: to
Antoine Lavoisier
Lavoisier, after meeting Priestley, recreated his experiment but only in reverse by adding mercury in a sealed container and started heating it until it turned into mercuric oxide then he measured the amount of air that was being absorbed by the mercury when it was being heated by doing this he realizes the air that was being absorbed and release by the mercury had nothing to do with phlogiston and that it didn't exist he then called it oxygen -
