A fused cast ceramic composition having superior corrosion and stoning resistance in the presence of E glass when compared with prior art compositions having comparable chromia content. The composition is a solidified fusion of from about 65 to about 98 weight percent Cr2O3, from about 0.75 to about 4 weight percent MgO and from about 1 to about 34.25 weight percent alumina. The invention also comprises the method for manufacturing the composition by fusing the appropriate materials at the required concentrations.
