Abstract

The bricks are given a black coating, at least in the vicinity of the heating elements and pref. on all external surfaces. The pref. bricks are magnesite with compsn. (all %) 92 MgO, 1 Al2O3, 2 Fe2O3, 3 CaO, 2 SiO2, and the pref. coating is a black stove enamel as used on oven plates. The coating improves the heat extn. from the elements, thus increasing total storage capacity. After normal heating at night for 8 hours, the brick temp. adjacent to the elements was 765 degrees C for a painted brick as compared with 810 degrees C for unpainted bricks.
