— The authors propose a new method in which the fact that a pottery or porcelain product is actually produced by the brand-holder company or by the ceramic artist (authenticity) can be easily verified, and at the same time, production of counterfeit products becomes difficult. The artifact-metrics are used in this method and as the material used in the method is transparent, the patterns and color tone created by the master artisan or ceramic artist are not affected. As the material is applied on to the product in the process of enameling or glazing, no additional work process is required for the master artisan or ceramic artist must take. Furthermore, because the method does not require UV rays or radioactive rays in registration and verification of products, potential hazards to the human body or product are eliminated, and no special skill is required in verification of authenticity. In this report, the authors indicate high feasibility of this method by showing results of elementary experiments.
— Artifact-metrics, authenticity verification, glass phosphor, infrared image processing.
