Written by W. G. Worcester and published in 1950. He was the first head of the University of Saskatchewan’s one-man Department of Ceramic Engineering and had a lab equipped with clay processing and testing equipment that many would admire today! He outlines clay geology in general, then the geological history of the province of Saskatchewan in that context. He describes the technology of ceramic materials, the major clays used in industry and the equivalent materials in the province. He submits hundreds of samples with physical test data clearly describing them and their locations (using extensive maps and diagrams). His work inspired Luke Lindoe, who continued it during the 1950s to 1970s. That inspired us to develop the testing methods used at Plainsman Clays to this day. And it gave us several clay quarries that have served the company for 50 years. It also alerts us that there of clay of much higher quality further east.
