WebbAlthough Gadolin accepted the phlogiston theory early in his career, he attempted to understand Lavoisier’s ideas. In a paper published in 1788 he tried to define phlogiston and admitted that the French explanation of combustion was superior to some phlogiston theories, but for a long time he was not wholly converted.
