[3 plat] Rings enbedded in pewter blob


#1

Hello to all. A Customer gave me here 50+ year old traditional
fishtail 900pt.-100irid. wedding set and a 1/2 rd. plat. band(unknown
alloy).poking out of a melted chunk of pewter. Rings appear to be in
good condition, just stuck. After cleaning off the soot and burnt
funiture (from a house fire), I’m left with a clean chunk of pewter
with plat. rings sticking out. I am looking for suggestions on how
best to proceed. A chemical solution solution? If nothing else, I
may Micheal-Angelo it and carve away anything that is not a plat.
ring.

P.S.- Thanks to all who responded to my last post, Revamping… Lots
of good info… love this place.

thank you. -rob

I’d be inclined to remove the bulk of pewter by mechanical means
(possibly heat) and the residuals through soaking in muriatic
(hydrochloric) acid.

Rob, I’d suggest melting the pewter and lifting the ring out. If the
ring is platinum and diamond it won’t be damaged by the heat. If the
stone is heat sensitive it will have been damaged by the original fire
anyway. Holding the piece above the melting point of the pewter you
should be able to brush off most of the pewter which remains. Good
luck. Jerry in Kodiak

Heat the pewter with a small torch while hanging the block of pewter
by the ring using wire. Then the pewter begins to melt away. Do nt
apply heat directly to the ring but only to the pewter. Once the blob
of pewter starts melting away, it will melt away quickly. Put an old
coffe can under it to collect the melted pewter.Without the can, the
pewter will hit the floor or table and splash all over everything
including your clothes. When you are left with only the ring with a
light coating of pewter on it and it is still quite hot, Grab the
wire holding the ring firmly with plyers and shack the ring away from
yourself… all excess pewter will dissapear that can be removed
without chemicals. Now take the ring and put it in sparex heated to
180 oF and leave it in the sparex with no other metals until the
pewter is completely gone.(other chemicals may work better) This
should work.
