Other Work
In addition to his isolation and study of germanium, Winkler investigated the analysis of gases. He published a book on the subject, Handbook of Technical Gas Analysis, in 1884. In that book Winkler describes his invention of the three-way stopcock. Clemens predicted the existence of silicon monoxide, SiO, and was the first to attempt to produce it by heating silica with silicon in 1890. However, he was unsuccessful because he was not able to heat the mixture to a high enough temperature using a combustion furnace. As no reaction occurred for him, Winkler incorrectly concluded that SiO does not exist, even though it was reported to have formed from the reduction of silica with charcoal three years earlier by C. F. Maybery. However, Henry Noel Potter, a Westinghouse engineer, repeated Winkler's experiment fifteen years later with an electric furnace, which enabled him to increase the reaction temperature by several hundred degrees and observe the generation of SiO.

Famous quotes containing the word work:
“While I do not think it was so intended I have always been of the opinion that this turned out to be much the best for me. I had no national experience. What I have ever been able to do has been the result of first learning how to do it. I am not gifted with intuition. I need not only hard work but experience to be ready to solve problems. The Presidents who have gone to Washington without first having held some national office have been at great disadvantage.”
—Calvin Coolidge (1872–1933)
“Just as a chemist “isolates” a substance from contaminations that distort his view of its nature and effects, so the work of art purifies significant appearance. It presents abstract themes in their generality, but not reduced to diagrams.”
—Rudolf Arnheim (b. 1904)
