Melting scrap silver
In this posting from Leonard (he was a bully but what a knowledge he
had!) he mention the use of soda as an better alternative for borax,
has any one had experience whit using this alternative when it comes
to sterling?
Before I blow out my basement workshop, is sodium carbonate
decahydrate the same as soda mentioned in this posting?
Re reuse of sterling, I my offend purist, but cutting out solder
seemse Is this not over the top, when I melt 100 gram of sterling,
cutoff pieces failedprojects (happen to me all the time) how much
solder will be in the mix? 1gram? The one gram holds 60 pro cent or
more pure silver, forget the 7.5% copper in sterling we are talking
about 0.4% When I melt used silver I pour the silver slowly in an
large metal bucket, or big flower pot of water, then I placed in an
acid bath for a day or so, the next day I use it for mainly wire,
casting or sometimes sheets. You have to change the water after each
pour, as you will notice there is always a dark layer floating on
top of the water after the pour, dust sand etc I assume.
Sawdust I first souk in borax and melt and pour in the bucket as
many times needed, most of the time two times
