<p>The method involves the making of a crude ceramic tile from a clay material. A first way of producing this tile involves the application of a layer of frit, which is made up of monolithic granules of a spheroidal form, on the crude tile. The tile with the layer of frit subsequently undergoes a thermal process, which includes the firing both of the tile and the frit. A second way of producing this tile involves the application of a layer of frit, made up of monolithic granules of a spheroidal form, on a tile which has been previously fired. Then the file with its layer of frit, undergoes a thermal process which includes the firing of the frit.</p> |
