    Default iron filings & sal ammoniac : pseudo welding

    Reading an old book today, it briefly mentioned a technique using sal ammoniac and iron filings to "weld" two pieces of metal together.

    Did some googling, didn't find anything terribly convincing - got the impression it is an old blacksmith's trick. Started turning up various recipes in my searches.

    Anybody here ever actually done this ?

    Hi Bill,

    Try these links. Some interesting reading here !

    https://chestofbooks.com/reference/E...ng-Part-6.html

    Scroll down to number 3523.

    Could be something borrowed from the Japanese Samurai sword makers. A flux used when beating two steel parts together. Damascus Steel making techniques.
