A bstract The principles of the process of fusing ceramic materials for abrasives and refractories are now rather generally known. The benefits to be derived from the additions of fused materials to a refractory are likely to be (1) an increase of chemical resistance owing to the greater density and lower permeability, (2) an increase of load‐bearing value of the product, and (3) a control of the kind and number of crystalline materials present in the grain as well as the proportion of glass contained. The term “flux” is not necessarily correctly used in connection with such fused materials, because it often applies only to a constituent which changes the proportions of the crystalline phases and does not affect the refractoriness or glass content.
