Several methods of freezing and thawing tests have been compared with each other and with the standard autoclave test with regard to type and rate of failure. Data indicate that the autoclave test alone is not sufficient to predict behavior of glazed ware in service, especially in the more severe climates. Glazes follow very definite laws as to rate of failure under conditions of freezing and thawing. Curves have been developed which indicate the nature of these laws very clearly. Considerable data have also been obtained on the effect of freezing on the porosity of brick and on the nature of failure of glazes.
