ABSTRACT This is a third Progress Report, based on data obtained in an extensive investigation of sagger clays for the purpose of determining the properties characterizing clays best suited to this type of service. The Report contains a brief description of the apparatus used in the determination of elasticity and transverse breaking strength at three temperatures, ranging up to 925°C. These data are correlated with thermal expansions of clays, as given in the second Progress Report, resulting in the formation of an empirical formula which indicates the relative resistance of saggers to failure due to thermal shock. The majority of clays show an increased rigidity or elasticity at the higher temperatures, but only those clays which are weak at room temperature indicate a marked increase in transverse strength.
