SOME PROPERTIES OF ENGLISH CHINA CLAYS*

Abstract
A study is presented of some of the properties of fifteen English china clays in common use commercially in the United States. Data are presented which may be useful in making substitutions for these clays, as well as furnishing a basis of correlation of some of the properties. A study of the base exchange capacities shows a general relationship to the transverse strengths of the clays in the unfired state.
