The strength of unglazed feldspathic porcelain test bars in air decreased with humidity at the time of breaking. Moderate vacuum increased strength. N 2 , CO 2 , O 2 , and H 2 were not effective in changing porcelain strength with respect to that in ambient air. Use of a so‐called compression glaze eliminated the deleterious effect of water. Several organic liquids, as coatings on unglazed test bars, were evaluated. Tests with acid and basic solutions indicated that porcelain strength decreased with an increase in the mole % of water present in the liquid coating.
