Ceramic clays and shales of the Atlantic provinces / K.E. Bell, J.G. Brady and L.K. Zemgals. : M38-13/78-21E-PDF

"The work reported forms part of the Mineral Resource Determination Activity of the EMR Minerals Program. Previous reports have dealt with the clays and shales of British Columbia, Ontario and Quebec. The results constitute a contribution to the knowledge base necessary to ensure the orderly and efficient development of the ceramic industry in Canada, particularly in the clay products field. Twenty-nine samples, representative of a variety of typical clays and shales indigenous to the region, were examined to determine their composition and salient ceramic properties. In addition, the forming and firing characteristics of ten of the samples were studied in considerable detail. The results made it possible to evaluate suitability of the material for manufacturing ceramics, to determine processing problems that might be expected, and to make assumptions as to the most likely geological formations containing the best quality of ceramic material"--Abstract, p. i.
