Hi all 

as for Bastian, tin-mercury reminds me mirrors (there is quite some
literature on its restoration, see also Hadsund, Per.The tin-mercury
mirror: its manufacturing technique and deterioration processes.
_Studies in conservation_ 38, no. 1 (1993), pp. 3-16) 

Also, 18th c furnitures such as Boulle ones may be inlaid with
tin-mercury plates and/or wires (on going research of ours). A bit later
than your 16th c mills... 

best

>> Hi, I discovered a peculiar alloy when looking at mill tokens from the 16th century. We have two stone casting moulds from Tallinn dated to 1537 CE (the have a date written on them). One of them showed traces of lead and mercury when analysed with a pXRF. We also have one of those tokens, which by the looks of it was cast with one of the moulds and the composition was about 45% Sn, 40% Hg, 10% Pb and 5% Cu (these are rough estimates, my pXRF is not calibrated to Hg alloys). It is possible that the token was cast later than the 16th century, but then it is not clear why it has been so worn down - it looks like it has been used/carried around for a while. My question: does anybody know any cases of tin-mercury alloys being used and could point me towards some literature about it? Best wishes Ragnar Saage University of Tartu ps. If I sparked someones interest in tokens, write me and I can share an article about them, that was written by a numismatic Ivar Leimus (Money or no money:
