In order to dehydrate and preserve fabric core lacquer wares excavated from Haiqu tomb site, a Han Dynasty tomb site in Rizhao city, nineteen lacquer fragments were selected and analyzed using stereomicroscopy, scanning electron microscopy and Xray to understand the materials and manufacture technique of the lacquers. No plaster layer was found between multiple ramie layers, a technique different from modern techniques. Water is easily deposited in these lacquers, making them susceptible to degradation. This study provides a reference for research into fabric core lacquer wares of ancient China
