—In this paper, we propose a new method in order to verify the authenticity of porcelain product much easier by using artifact-metrics technology. In our method, counterfeiter cannot make copied product even if they could use same materials and tools which were used by the brand holder company or the ceramic artists. This method uses transparent glass phosphor powder to apply characteristic information on the surface of each product during glazing or/and painting on daily production, so that color tone created in the furnace is not affected. Our method requires no additional work for master artisan and no sophisticated skills for buyer. Besides, glass phosphor has no potential hazards to the human body and environment. In this paper, we indicate high feasibility of our method by showing results of some experiments. We also try to burn invisible information (QR code) onto the surface of each porcelain product.
