Ancient grave goods in East and Southeast Asia were sometimes wrapped in cloth before they were buried. I have a Neolithic calcified jade bi from North China that has the marks of a cloth wrapping deeply impressed in the stone. I don't have photos of that but here is one of a bronze bowl from southern Vietnam that is about 2000 years old. So far it hasn't proved possible to discover what the material was; probably cotton, but I wouldn't rule out the possibility of it being some kind of silk, either imported or locally produced.

I think this practice tells us something about the value that the living placed on the items that they buried with their dead.
