Testing supply

[jmdlcar]

What testing supply do I need to buy after I remove the gold foil from the fingers? I just don't want to lose any gold when I get started again. I know I won't get back what I lost but everything helps. So if someone can help me and tell me where to get them. I did a search could not find anything.

What do you want to test for? If it is the presence of gold you should make or buy stannous chloride.

Where is the best place to buy it?

I make my own fresh as stannous chloride crystals can go bad with exposure to air over time. I use pure tin (but you can use 95/5 lead free solder) and hydrochloric acid.

lazersteve on this forum sells pure tin, just find a post by him and follow the links in his signature line.

Thanks Oz I will order it and other thing from him the first of the year. I already have his DVD on refining gold fingers.

I had some rosin core solder 97.3% tin 0.7% copper 2.0% rosin flux core will this work for a start? How much should I use if it will in grams?

You could also try Radio Shack's 96%tin/4%silver solder. Just a thought...

Well... How about a fish & tackle store; tin weights, like the ones for fishing. I understand that a lot sell them instead of lead.
