A bstract Powdered‐glass samples were exposed to an atmosphere of 98% relative humidity at 100°F. for three days. Commercial bottles and laboratory melts which systematically covered the field of container compositions were tested. The resulting gain in weight of the glasses, which is a function of their chemical compositions, can serve as an accelerated test of the rate of attack by water vapor. The determination of the permanent gain in weight of the treated samples after they have been dried and the appearance of the products formed on the surface of the glass powders provide further useful data.
