…I have used your products before and am grateful you are out there! Last month I bought some silver wire with the expectation of doing some soldering.

Thanks for the nice comment. The silver you have sounds like sterling silver, which is used to make jewelry. It is not pure, but contains either copper or nickel, added to the silver to make it more durable. Do not use Nickel for making colloidal silver.
