In an improved method for the production of slabs of ceramic material, the starting mixture is enclosed between two sheets of cardboard or paperboard, subjected to vibrating compression under vacuum. The cardboard or paperboard being thick enough to absorb the excess mixture water prior to the transfer to the subsequent drying and firing stages, said sheets of paperboard being removed before said drying stage, so that the rough-formed slab is dried resting solely on a porous fabric or felt, and baking is performed while keeping the dried rough-formed slab in contact with the oven surface solely by means of a temporary protective layer of refractory material (engobe).</SDOA B>
