kennedy759 Valued Member United States 240 Posts	Posted 01/25/2023 04:06 am anyone attempt to melt down scrap silver into bars? Friend has a bunch of scrap silver recovered from electric devices and wants it melted down. I see you can buy most of what is needed online, molds, crucible with handle, borax flux etc. The melting point of silver is 1700 F, that my oxy/ac torch should achieve. anyone try it?

Molten silver absorbs oxygen from the air and it bubbles out as the poured metal solidifies. It makes for an interesting cratered texture but it's probably not what you're looking for.

Anthony86 Valued Member United States 59 Posts	Posted 04/03/2023 9:21 pm I've melted silver and poured into bars. If your melting silver that is not .999 silver such 90% coins, you have to use nitric acid and distilled water. I used 1/4 acid and 3/4 distilled water. You definitely need glove and mask. Once all the metal is dissolved, your left with a paste at the bottom that is the silver. You need to rinse the silver multiple times with coffee filters to remove the impurities. Let it dry and your left with .999 powder. Now it is ready to melt. Report this Post to the Staff
