An Improved Method for Measuring the “After-Contraction” of Refractory Materials

JSGT_1933_V17_T320_T323

Our improved method consists in standing the test-piece on three steel balls on a steel plane table. A steel ball carried at the top of the test-piece bears against the plunger of an Ames dial gauge, and the gauge is standardised against steel rods of known lengths. An accuracy of one unit in the second decimal place is claimed.
