—We explored the feasibility of applying artifact-metrics to authenticate and identify valuable, fine lacquerware. We used a model method to consider the feasibility of this technique. In this method, lacquer liquid containing fine particles with optical properties was utilized several times to coat the base material for lacquerware so that the fine particles randomly occurred in the coating film of the lacquer. As information resulting from the optical properties of fine particles can be obtained in a contactless manner by photo shooting, the risk of degrading or scratching the surface of lacquerware by using this method is low. In the experiment using the above model, we used clear lacquer liquid that contained glass phosphor powder and coated it onto wooden base material to make sample lacquerware. We acquired an infrared (IR) image of each sample by optical excitation and found that the fine particles randomly occurred and formed a layer. The intensity of the IR light emission was determined based on the number of times the lacquer liquid was coated on the wooden base material.
