Four of these fired to a buff colour. Three clays showed evidence of scumming and, if used, would have to be chemically treated to counteract their content of soluble salts. Five clays were judged to be of poor quality because of high drying shrinkage and a tendency to black-core when fired rapidly. They could be used with the addition of grog to facilitate drying and firing. Seven clays were not satisfactory for the manufacutre of building bricks and sewer pipe. - Authors.สาระสังเขป: Thirty-five field samples of clay were collected and tested in the laboratory for possible use in the manufacture of common brick, face brick, and sewer pipe. The following unfired physical properties were determined: colour, workability, water for plasticity, grain size distribution, drying shrinkage, and dry strength. Reaction of the clays to high temperatures was determined by a pyrometric cone equivalent test and a thermal expansion test. Individual samples of each clay were fired in a laboratory kiln to four or five temperaturos between 900 degree celsius and 1100 degree celsius and tested for firing shrinkage, fired strength, water absorption, fired colour, and hardness.
