Excerpt from The Properties of Some Stoneware Clays The work was begun in June, 1917, before the Bureau of Mines ceramic experiment station at Columbus, Ohio, was established, and was later continued at that station. The writer is indebted to A. S. Watts, quarry technologist of the bureau, under whose direction the work was undertaken. The Pennsylvania geological survey assisted in obtaining the clays in cluded from that State. The samples of Ohio clays and the sections of the beds sampled were supplied by Mr. Wilbur Stout, of the Ohio geological survey.
