    So.. I went with the pre 1992 coin route. Worked out nicely!

    Amazing Nick. Three questions:
    Is that a Delft clay or lost wax casting?
    Is the pin fixed or cast separately?
    What would you call it? Dennis.

    Morning Dennis,

    Thankyou and in answer to your questions, it was only the pin that I created and added.

    It's a centuries old Medieval ring brooch. The terminals originally had paste stones in them but as you can see, they've been lost to history.

    My customer collects these medieval brooches so wanted the pin replaced. Originally it'll have been made from iron or bronze.

    The pin was cast in self clay, and it rotates as it would have originally done. The main body of the brooch is also bronze.

    Here's a couple of pics to best describe the process. Once I'd cast the pin then I filed and refined it so that it would fit into the recess on the brooch ( look closely far right hand side )

    Cheers,

    Nick

    Great restoration and I see now why you didn't need much bronze. Dennis

    Cheers mate. Was only a little fiddly job but nice to have a dabble with a bit of bronze. The customers happy, so theres now going to be lots of repeat business coming my way.

    I enjoy restoring old artefacts, straightening coins, etc just as much as making new jewellery to be honest.

    Cheers,

    Nick

    Further to me waffling on about bronze then, has anyone any experience of soldering it?

    If so then what kind of solder and flux is used?

    You can get dedicated solders for base metals on Ebay. They will be an approximate match, but better than silver in appearance.

    If usingborax as flux, a good pinch of Tenacicity No5 will be an extra safeguard againt oxidation. Dennis.
