While the raw lacquer is toxic, once it dries it is insoluble to all chemicals; and its toxins are trapped inside. Thus there are no health worries, and lacquer ware is impervious to humidity, heat, acids, and alkalis. It is a natural insulator, and remains perfectly preserved even when buried underground for ages. Few other art objects can compare.
賴作明表示，生漆本來是具有毒性的液體，一旦乾固後，便不被任何化學藥水所溶解，漆本身也不再散發出毒氣，安全上沒有問題，又具有防潮、耐熱、絕緣、不畏酸鹼浸蝕的特性，埋藏土中歷久不腐，甚少藝術品能及。
