A bstract This investigation employed the following drying tests: (1) in the presence of CaCl 2 , (2) in air circulated at 100°F, (3) in air circulated at 225°F, and (4) in a humidity drier, employing 129°F, dry bulb, with 85% humidity for two days and decreasing humidity to bone dryness in five days. The trials were fired under regular plant conditions and stored as follows: (1) in a closed chamber with adequate supply of CaCl 2 , (2) in outside weather, winter and spring, (3) alternate soaking in water for two days and drying to 5% of total absorption for the period of test, and (4) in a saturated atmosphere. Data on modulus of rupture, absorption, and porosity are assembled in tables and graphs for comparison, indicating marked influences on these properties both by drying and storage treatments. Explanations of the results are suggested.
