The history and purpose of the investigation are outlined and detailed reports are made on (1) the results of air elutriation and coöperative sieve and chemical analyses of the nineteen feldspars being studied, (2) coöperative determinations of softening point, and (3) true specific gravity. The paper also includes a report on tests of mechanical strength, light transmission, porosity, volume shrinkage during firing, and thermal expansion of whiteware specimens in which the feldspars being studied were the only variable component.
