Abstract
24,837. Wellman, S. T., and Wellman, C. H. May 22, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Drawings to Specification. Firebricks for use in the walls of coke ovens are made of magnesia, either pure or with a proportion of clay or silica. Such bricks may be made from magnesite, which is calcined, ground, sifted, rendered plastic with water, moulded, dried, and burnt in a kiln. Their conductivity is greater than that of ordinary firebricks.
