Silver derived from copper and its derivatives, including copper sulfide, requires different handling and refining techniques than silver minerals taken from zinc deposits and lead sources.

    The Refiner's Fire a lesson from the process of refining

    He explained that in refining silver, one needed to hold the silver in the middle of the fire where the flames were hottest as to burn away all the impurities. The woman thought about God holding us in such a hot spot; then she thought again about the verse that says: ‘He sits as a refiner and purifier of silver.’ (Malachi 3:3) She asked the silversmith if it was true that he had to sit there in front of the fire the whole time the silver was being refined.
