A brief review of the literature on the fluxing action of different metallic oxides on clays is given. A series of mixtures of what seemed to be the “dirtiest” clay of four obtained, with varying amounts of pure calcium carbonate which passed a 150‐mesh screen was made up into briquets and physical properties were studied on the unfired and fired specimens. The firing was done at four temperatures, 1800°F, 1900°F, 1950°F, and 2000°F. Properties observed were fusion point, drying and firing shrinkage, crushing strength, and porosities of the fired specimens. The principle of the Armstrong volumeter used for porosity determinations is explained. The results obtained indicate possibilities of materially improving qualities of brick now being produced from so‐called ordinary clays but only after a very considerable amount of further work is done.
