Direct bonding in burned magnesite‐chrome refractories is described as a mineralogical phenomenon and as a factor governing brick properties. Hot‐load tests are recommended as a supplement to hot modulus tests to obtain a meaningful picture of high‐temperature strength. The importance of purity of ingredients is thus made more apparent. Direct‐bonded brick from open‐hearth service are shown to have a lower level of slag absorption. The result was reproduced in a unique laboratory diffusion furnace and a relation between silicate buildup and original brick purity is established.
