METHOD OF OBTAINING SLABS OF PETROUS MATERIALS COMPRISING TWO LAYERS OF MATERIALS HAVING DIFFERENT AESTHETIC QUALITIES AND THE SLABS THUS OBTAINED

摘要

The invention relates to a method of obtaining slabs of petrous materials, such as marble or granite, which are formed by two layers of materials having different aesthetic qualities. The inventive method comprises the following steps: (a) two blocks of petrous material are formed which have different aesthetic qualities but identical dimensions (b) said blocks are cut to produce equal pieces (c) mixed blocks are formed by using a suitable product to affix pieces of said two materials, horizontally and alternately, one on top of the other and, optionally, said pieces are reinforced (d) the mixed blocks are overturned such that the pieces formed by said blocks remain in the same position as at the end of step b the mixed blocks are cut to produce pieces that are formed by two layers of petrous material having different aesthetic qualities and (f) the aforementioned pieces are dried, smoothed and, optionally, reinforced. The invention also relates to the slabs obtained using said method.
