(57) A method for manufacturing construction elements such as ceramic tiles and slabs, consisting of pressing in one or two stages a mass consisting of at least two ceramic materials generally in powder form at least partially mixed together and having different properties, generally different colours, followed by firing of the pressed product, characterised by comprising the following operative steps: separately preparing bodies of generally irregular form starting from at least one ceramic material generally in powder form having properties different from those of said at least two materials of said mass; adding said bodies to said mass before the final pressing; and subjecting the product to a surface finishing operation before or after said firing step.
