Potentiality of common clay in ceramic industry

An attempt was made to fabricate different ceramic items made of common clays. The fast depletion of higher grade china clays and progressive increase in the cost of fuel necessitated the development of ceramic bodies by incorporating abundantly available low-cost, inferior grade ceramic clays fired at a low temperature but without compromising with the desired properties. With preliminary processing, the physical properties of the clay—both unfired and fired, were systematically investigated in detail. The utilisation of the common clay along with other ceramic ingredients in right proportion in the production of various types of semi-vitreous and vitreous articles was found to be quite viable
