I don't see any spectrometer, diffractomer, or xray analysis in that post. Did I miss it somehow ?

- peeters 7y agoNot OP, and it's an article about an article about a study, but I think this is where the analysis would be mentioned: > According to Phys.org, the researchers used “lead and tin isotope data as well as trace element analysis” to identify where the metal was originally mined. What they found was totally unexpected. Phys.org article in question in here but says the same thing: https://phys.org/news/2019-09-enigma-bronze-age-tin.html https://phys.org/news/2019-09-enigma-bronze-age-tin.html I don't have access to the actual study contents.
- avip 7y agoI've linked to it above. It's in Dutch but the analysis is there.
- boomboomsubban 7y agoThe English copy is there too, though that site is a nightmare to navigate. Here's the direct link. https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0218326 https://journals.plos.org/plosone/article?id=10.1371/journal...
- pvaldes 7y ago> “lead and tin isotope data as well as trace element analysis” to identify where the metal was originally mined. A problem could be that metals scrappings can be recycled. Who grants that a tin was not part of a ship's hull before?
- boomboomsubban 7y agoThey were ingots found in shipwrecks and do not appear to have the characteristics of a metal reused.
- hinkley 7y agoIs this essentially a superset of the techniques they use to identify gold bullion? I understood they have a map of trace elements by mine so that gold isn’t really fungible (if stolen or used for criminal activity, they can figure out where it came from and connect the dots).
- pg_is_a_butt 7y agoYeah, it's not like you could melt it down and mix in anything you want
