Thanks for the link, but my digging these days relates to native gold.
I`m assembling a list of artifacts from the Qumran settlement and (separately)the Caves, and looking for any connection. E.g. any copper scraps from the Treasure Scroll, though what a poor religious community (or a pottery plant) might have in common with the Scroll list is debatable. Whether any of the inkwells from the settlement contained red ink as a number of Scrolls used. Remains of the blue-bordered cloth wraps in both places, etc. etc. Odd that the caves behind the settlement never yielded any scroll scraps, but then those Bedu are thorough. :-)
