The amount of titania a clay can contain without appreciably lowering its refractoriness was determined. A soft flint fire clay, a hard flint fire clay, and a kaolin with varying percentages of titania added were fired to 2840°F. and examined. The influence of titania on the glassy material formed was found to be the same in each of the three clays considered. This was indicated by both apparent porosity determinations and examination of thin sections under the petrographic microscope. The most rapid increase in the development of glassy material occurred when from 3 to 4.5% titania was added to the clay.
