Koummya silver sheath
Out of the Goodness of My Heart went back to chat with the guys where I used to work, & sit in on a technical-marketing meeting (sorry, just can't keep quiet).
Oh, yeah, the lab happens to have an Xray fluoroscope = metal analysis (except carbon) with no harm to the object. Happened to have my Koummya along & got the silver sheath analyzed. No surprising results. It is essentially coin silver, about 90%silver 10% copper with residual lead from the refining process & a few residual elements. For any other odd metallurgists out there the complete chemistry was: 89.54% silver 9.32% copper 0.66% lead 0.21% silicon 0.13% tungsten 0.15% zinc. Someone who studies such stuff might be able to tell from those residual elements, Si, W & Zn, from what mine came the silver. Whatever the age, the silver rings on the sheath are well worn from someone carrying it awhile. Might the inscription be legible enough for any of you gentlemen to read? |
