A Study of Different Drying Condition for Conservation of Lacquer Wares and Durability of Urushi Lacquer Coats with Enzyme Addition

This study attempted to evaluate the durability of the lacquer coating by comparing the changes in physical properties and chemical composition before and after deterioration with various drying conditions and samples added with Laccase enzymes because it deteriorates in ultraviolet rays. Through studies according to each condition, the durability of the ultraviolet-deteriorated lacquered coating film showed stable results in 90% of the drying conditions, as well as the surface, cross-section, and chemical composition. It was found that the smaller the ratio of uruciol and lactase, the less the color difference and gloss change, and the less the chemical composition is affected, but the more cracks are. Bacteria had the best durability in evaluating physical properties and chemical composition when using bacteria lacquase from oyster mushrooms.
