Several brick of intermediate duty, high duty, and superduty quality made by three different manufacturers were tested in the load equipment. The test brick was brought up to a temperature of 1400°C. (2550°F.) in 3 hours, soaked at this temperature for 1/2 hour, and then pressure was applied at the rate of 31/2 lb. per sq. in. per minute. Thus a pressure of 100 lb. per sq. in. was applied in 30 minutes. The effect of P.C.E., porosity, and lamination cracks on flow characteristics are described. It is shown that the increasing‐load test is more rapid than the constant‐load test for determining flow characteristics.
