摘要： A composition of matter which is useful by a particular method for forming an electrically conductive glaze upon the outer surface of a ceramic mold form wherein the combination includes approximately 25 percent potash feldspar, approximately 22 percent flint, approximately 7 to 8 percent calcium carbonate, approximately 1 to 2 percent ball clay, approximately 2 to 4 percent kaolin, approximately 5 percent barium carbonate and approximately 35 percent red iron oxide, all percentages being taken by weight, the method including the addition of an amount of flocculant such as 20 percent magnesium sulfate solution to control the viscosity of the solution and thereby control the thickness of the layer formed upon the external surface of the ceramic mold form, the method also including preferably the spraying or dipping of the mold form in the resulting solution for coating thereof as well as the firing of the coated ceramic mold form in a furnace of approximately 2200 to 2300 degrees Fahrenheit for approximately a 30 hour cycle.
