Method for manufacturing tiles having their exposed side provided with depressions and reliefs to reproduce the appearance of split quarrystone

摘要

The method comprises the following operations:in a usual mould, forming a crude tile from an atomized powder mix, that mould punch intended to create the exposed face of the tile reproducing the appearance of split quarrystone or of a non-flat surface;drying the thus formed tile in a continuous dryer in accordance with a usual drying cycle;applying on the exposed side of the dried tile at least one layer of coloured atomized clay or of pigment in powder form, to at least partly cover said side of the tile;subjecting the exposed side of the tile to the action of an air stream at an incidence angle tending towards zero;kiln-firing the tile treated in this manner in accordance with a usual firing cycle.
