ABSTRACT: Large reserves of clay suitable fro low-duty refractory products are present in southwestern Indiana, as shown by PCE (pyrometric cone equivalent) determinations on a group of 310 samples. The great amount of refractory products used in Indiana would seem to warrant a larger output of refractories made from Indiana clays than the present output. A tentative correlation of refractoriness and clay mineral composition is based on results of mineralogic and particle-size determinations.
