Collectors often want their ancient beads to be clean and
in perfect condition. But, washing and repairing ancient beads
may be a mistake because it makes old beads look new.

The Warring States bead on the right in Floor's post
appears to be new also. But it is not a new bead.

The problem is: Inexperienced AND advanced collectors
become suspicious that excellent antique examples may
be copies when old beads have little or no patina.
