by P.C. Sweet, 107 pages, 30 figures, 3 tables, 1986. This report contains the results of tests on the properties of clay, shale, and related materials required to evaluate their potential use for ceramic and non-ceramic products. A total of 75 samples, collected in 29 counties and one independent city in Virginia between May 1981 and July 1984, were tested. These tests indicate that the material represented by 51 of the samples (68%) is potentially suitable for use as structural clay products (building brick, floor brick, structural tile), super-duty and medium-duty refractories, or lightweight aggregate.
