Excerpt from Clays and Shales of MinnesotaThis bulletin gives the results of an investigation of the clay resources of Minnesota made during 1912 and 1913. In general the Object of the work has been to assist in the development of the clay resources of the State. The broader problems of Ceramics are treated only incidentally, but some of the important scientific conclusions Of the American Ceramic Society, of the Bureau of Standards, and Of surveys of other States are brie¿y reviewed in order that they may be more readily available to those whose chief interests are technical and commercial. A more extended treatment of the scientific results Of the investigation will be published later.Specifically, the Object has been to investigate the brick supply for every town of or more inhabitants and for every county in the State, to ascertain the extent of several deposits now developed at only a few points, to find new deposits, and to determine the qualities Of these deposits and of certain mixtures so as to ascertain whether it is possible to produce refractory wares, pottery, paving brick, and other high-grade products.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
