Dear Tom...I do this for my silver waste on the instructions of the
chemistry dept ..what I actually do is to have a couple of old winchesters
with NaCl added to them you put the waste in the bottle this forms silver
chloride which is insoluable and if left overnight settles out you can
then decant to sink with water and recharge the bottle after a while I
guess you must do something with the bottle as it fills with silver
chloride but  this takes ages   Hope this helps Mary
