"The term "Diaspore" as used in this paper will be used to mean the diaspore clay from which refractory bodies are made. The pure mineral Diaspore (Al₂O₃ . H₂O) has an Al₂O₃ content of 85%, while the best grades of diaspore clay run from 76% to 79% diaspore. Diaspore clay consists of a varying percentage of diaspore, ranging from 60% to 79%, and the remaining percentage as clay. The most objectionable impurities which occure sic in diaspore clay are alkalies. The chief source of diaspore is the central part of Missouri. It occurs in pot hole formations accompanied by "flint" and "burley" clays, which are nothing more than clays of lower Al₂O₃ content"--Introduction - Diaspore, page 1.
