Natural and heterogeneous products

Natural diversity inspires with its uniqueness. At the same time, they present manufacturers with particular challenges in terms of quality assurance, as inclusions, cracks, discoloration or glaze defects can impair the appearance and lead to rejects, rework or complaints. In addition, there are typical processing defects such as burn marks, grinding marks, polishing defects, chipping or uneven coatings, which reduce the value of a product.
