Study on temporary protection of ivories,buckteeth and antlers unearthed from Jinsha site

Besides numerous cultural relics such as metal vessels, potteries and stones, piles of ivories, ivory vessels, buckteeth and antlers were excavated at Jinsha site near Chengdu. But these remains were found corroded hardly and easy crazed shortly after they were unearthed. So a great effort was made to protect them from further damages. Through a series of experiments, a cohesive resin was selected, with which an on - the - spot reinforcement became possible.
