The history, development, and properties of chrome and diaspore brick are discussed. The plan for this investigation was the determination of (1) softening points of various mixes, all of which withstood cones 33 to 34, (2) workability of mixtures, wherein it was found that bars of soft mud were workable with difficulty while no trouble was experienced with dry‐press, (3) porosity and shrinkage on reheating; slag action and spalling. Increasing the proportion of diaspore increased the shrinkage while the absorption remained about the same in all cases. Various slags from different sources were used in the investigation, and it was found that a small per cent of finely‐ground chrome ore cut down slag action on diaspore while the addition of diaspore to chrome increased its resistance to spalling action; conversely, the addition of finely‐ground chrome to diaspore increased its resistance to spalling action.
