Black body and black glazes for tile production

Summary

There is an increasing tendency to use coloured glazed roofing tiles. In the case of damage to the surface of the roofing tile, it is useful to show a body of the identical colour of the glaze.  The possibilities are discussed for an  economic production of black bodies having a common illitic batch with additions of a secondary material, the paramagnetic tailings of a gabbro beneficiation, and the development of an adapted black glaze, which also utilises the tailings from Egyptian gabbros.  13 refs.
