The surface sawn is obtained directly from the mechanical cutting of the Trachyte slab. This processing is the ultimate result of a mechanical process. The sawn surface, in fact, is obtained with mechanical movements of the blade, disc or wire on the outer surface of the slab. The surface has then slight irregularities, while color and design are left unchanged. The final effect is of a natural stone, aged, ideal for those articles intended to be inserted in external environments or as flooring.
