A method for the production of refractory bodies of magnesium-chromite oxide, of low porosity consisting of; A) mixing about 40% to 80% calcined magnesite (periclase) with about 60% to 20% chromite to produce a 100% mixture of magnesite and chromite; B) said fine mixture containing a combined total of up to about 5% ca0 and si02 by weight; C) the weight ratio of ca0 to si02 being at least 1: 1; D) configuring said mixture in refractory bodies Y E) calcining said bodies at a temperature of about 2950º f (1621º c) at least.
