Experiments on oxygen by Scheele. 18th-century illustration of a set of experiments on oxygen described in the 1782 edition of the book 'Chemische abhandlung von luft und feuer' by Swedish Pomeranian chemist Carl Wilhelm Scheele (1742-1786). This book was first published in 1777, with the English edition of 1780 titled 'Chemical Observation and Experiments on Air and Fire'. Scheele discovered several new chemical elements and compounds, but was unlucky in that his contemporaries often published their findings before him. In the 1770s he discovered the gaseous elements chlorine and oxygen, with the discovery of oxygen published in this book. Priestley and Lavoisier published their findings on oxygen before Scheele. Here, the illustrations show experiments using burning candles to test different aspects of air, and chemicals being heated to produce oxygen. | |
