[QUOTE="treasureman, post: 158550, member: 3793"] Bit of a dilemma here. I have these beautiful ancient pure gold coins that were solded into a brooch some time ago. I want to remove these coins from the brooch the best way possible. ive read a few trestments. Heating to a degree where the solder melts and the gold doesnt. Releasing the coins. or ive read that an acid bath if pure gold so the solder disolves and the gold remains intact. a jeweler told me he would file in between the brooch and the coin but to me that sounds quite abrassive and damaging. would love to here your advice/ knowledge to remove these the best way possible. thanks in advance. staining from the other alloys is getting quite bad where the brooch is joined[img]https://www.prospectingaustralia.com/forum/img/member-images/3793/1432861315_img_20150529_110122.jpg[/img] [/QUOTE]
