I did not mean to speculate or imply that the DSS were written on re-used
materials.  I only wanted to raise the point that one should be careful
when doing "scientific material analysis."   I know that infra-red and
digital enhancements can be used to restore erased text.  DNA testing,
Carbon-14, or other tests are only pieces of the puzzle.  Other data must
be used to establish a reliable date.
