Written by W. C. Worcester. He 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.
