When ground to 20-mesh and mixed with 37.0 per cent of water, it made a plastic paste, that stood a fair rate of drying, and that shrank 10.0 per cent in drying and a like amount when vitrified, giving a total shrinkage of 20.0 per cent. The air-dried mud showed a tensile strength of 161 pounds to the square inch (only one test). It burned to a hard, compact body, nearly vitrified at cone 1 (2,102 degrees F.), without much farther change towards viscosity at cone 6 (2,282 degrees F.). This is a common-brick and drain-tile clay. The analysis of this clay follows: Per cent. Moisture at 100 C. 3.75 9.32 52.10 22.48 6.88 0.65 tr. 1.45 Combined water Silica Alumina..
