what will silver solder do to a mix of lead
small scale like say 10#pot or so
I am talking very small amount to like 2"of solder :castmine:

No one would have known had you not spilled the beans!

The silver Solder I use
Is either 6 or 8 % silver , less than 1% atimoney , less than 1% copper in some brands and the rest tin

So just think about it as you are adding a little tin to the mix

So IMO you didn't add enough to change the alloy enough to see a differance

To up the tin content of your alloy just 1% in a 10 lb batch , you would need to add just over 1/10 of a roll or about 10" - 12" depending on the brand and dia

I sometimes get Silver solder scraps , I just consider them Tin

2" isn't enough to do anything.

It would be enough to make a werewolf sick, and really pizzed off.

guess I'd have to shoot him a time or two
just kinda playin with the stuff addin it
it did make the mold open harder and the boolits were full and nice

I have used a lot of lead-free solder and silver-solder (4 and 6% Ag) to alloy with lead. As advised above, just consider it tin and ignore the silver.

2" of solder in a 10lb pot is really a vanishingly small amount, but sometimes a very small amount of tin will make a noticeable difference. I can very easily detect the addition of 1/4% tin in the pot, and if I need to add tin, I never need to add anywhere near the commonly recommended 2%. Now, 1/4% of a 10lb pot is approx 1/2oz of lead-free solder.

Your mileage can be expected to vary, but the addition of tin is made solely to address problems/deficiencies that affect the end result. If excellent results can be had with 1/4%Sn addition, then there's no need to add any more than that. Add only as much as needed. Good luck.

the add will not make the batch harder ...will it ?????

Anytime you alloy anything with lead, it always makes the lead harder.

Some things make the lead a lot harder, some not much harder. Adding a small amount of solder to a pot of lead will not crank up the hardness very much, but it often markedly improves fluidity, fillout, and reduces drossing. Good luck.

Just remember that Ivory Snow was 99.4% pure.
