A new technique of coating ceramic ware using two‐step drain casting is described in which small alumina crucibles are drain cast followed by drain casting a magnesia coat in the same mold. Cosintering at 1500°C resulted in ware defects unless heating schedules embodying arrests at lower temperatures were used.
