Dear Horacio,
There is a good article on dating of tin cans and
glass bottles written by a geologist witht he U.S.
Geological Survey. It will take me a few days to find
out the reference but I will work on it. He was
working on the geology of old metal mines in the
western US and found that the trash was the only good
way to date the time of operations.
Yours, Robert G. Schmidt, retired geologist
