JPL: Interesting metallurgical post:
Guys,
I have never seen any silver pieces with any hint of a splash.
I'm not sure if liquid metal would adhere to the silver over the long term.
With the copper QVIESCAT PLEBS coins I have yet to see a truly embedded piece of brass/metal.
What I do see is liquid metal that sometimes was spread very thinly over the planchet and has had great adherence properties while other droplets are thicker and sometimes have contracted a bit to form a physical outline around the splash.
Then there are those that have a shallow crater like appearance with the detail of the strike still showing. My guess is that the brassy metal is no longer there.
Just a gut feeling -- the "gold" splash was in a higher metal -- yeah it wasn't gold, but it looked it. Would it almost be insulting a silver piece to have a brass splasher in it, since it would be an inferior metal to the coin? Obviously a real gold splasher would have been cool, but expensive to produce.
I'm not sure of what the metallurgical process would be, if brass would bind strongly to silver during striking or not as it did with copper. I haven't seen any evidence on any of the silver St Pat's that they even tried to make one with a splasher -- and I don't readily recall ANY coin from the era that was silver with any sort of splasher in it, so there might be some metallurgical reason why it doesn't happen.
JPL: I have never seen any CONFIRMATION what the yellow metal is in these splashers or the process that created these splashers - be DEFINED?
