Recycling 800 silver in pure silver

Since silver is a malleable precious metal, it's necessary to combine it with another metal (copper is the most commonly used metal) in order to increase its mechanical strength.

Silver 800 is the poorest alloy entitled to the term pure silver. Its brilliance is not comparable with that of sterling silver (or silver 925) or that of silver 950.

Beyond silver 800, the problem of recycling arises for all silver alloys, residues of the manufacture of silver jewelry : dust, chips and pieces of silver solder that are on the jeweler's workbench.
