Most of the refractory raw materials being used in Nigeria are imported from American, Asia, China, and some other countries. Due to the large deposit of clay available in Bauchi state that are used in the production of locally made pot, there are limited literatures on the study of Bauchi state clays, to examining the mineralogical parameters especially refractoriness for application in steel smelting hence the purpose of this review work. The clays collected from various places had been analyzed based on chemical composition, cold crushing strength, Bulk density, thermal shock resistance, porosity, and Refractoriness from relevant literatures.  The result obtained can be compared with the known standard of refractory materials as in table 1. In order to achieve high quality metal, the refractory clay obtain in a single site have to beneficiated with other refractory clays from other site or blended with some other additives, to improve the physical, mechanical and chemical properties of the final products.
