Wason became a professor of chemistry in 1764 and was elected a fellow of the Royal Society in 1769 after publishing a paper on the solution of salts in Philosophical Transactions. Later, he published his Chemical Essays in five volumes. These are intelligent and lucid but derivative, revealing Watson as an intelligent layman not a research scientist. They show a particular interest in applying science to manufacturing processes and a belief that chemistry could help to realize Britain's industrial potential. Watson worked on the efficiency of gunpowder and discovered that a thermometer in which the bulb was painted with black ink gave a higher reading than an ordinary thermometer. His account of the lime processes used in tar and lead smelting and his work on pit coal shows a particular interest in metallurgy. (ODNB).
