These tusks have been buried underground for thousands of years. If they are exposed to the air suddenly, they are easy to lose water, lead to deformation and cause great losses.

Therefore, in the process of archaeological excavation, workers need to protect the ivory while excavating. They use the temporary protection method of wet towel and plastic film to keep the moisture of the ivory.
