Includes bibliographical references. “Canada, in general, lacks good-quality days and shales useful to the ceramic industry, particularly high-quality kaolin and fire day deposits. British Columbia is no exception, but there is a wider variety of days there than in many of the other provinces. Common brick, facing brick, drain tile, building tile, flower pots, pottery, sewer pipe, flue liners, and conduits are all manufactured from British Columbia's common clays and shales. Some local fire clays are used in the manufacture of refractories, brick, tile, sewer pipe, conduits or flue liners, and a few stoneware clays are available. There are also useful deposits in certain areas where the potential market is now limited, and in the northern areas of the province where transportation charges are high. For purposes of this report, twenty-two samples were selected as being typical of B.C. clays and shales available to the ceramic industry of that province. The samples include common clays or shales, stoneware clays, and fire clays. Some of these materials are being used commercially, and all can probably be used for the manufacture of ceramic products, some with difficulty. In the present study, ceramic properties and mineralogical composition are investigated, problems associated with processing are discussed, and the results of differential thermal analysis and X-ray diffraction analyses are correlated with ceramic properties"--Introd., p. 45. gccst Ceramics Dean, R.
