Syllabus of Clay Testing: Part 1

Description: From Introduction: "This presentation (pt. 1) is what might be termed a qualitative syllabus, in that uses only are indicated, no attempt being made to evaluate a clay quantitatively, that is, to grade for particular uses. In part 2, which is to follow, the work will be amplified both qualitatively and quantitatively. In the first, preliminary tests are made to eliminate from consideration all nonclay minerals or clay minerals containing such large amounts of impurities as to render them unfit for normal uses and also to make a broad general classification of the clay minerals into the kaolinite (shales and clays) and montmorillonite groups. In the second step, the main tests, divided into two general headings, ceramic and noncermaic, are detailed."
