I've been having some problems using the Argentium® solders. I tried just about everything I could think of. I made sure the surfaces matched well. I made sure my silver was clean and scrubbed it down with steel wool. I tried several types of flux. My easy and medium solders worked just fine. It's taken me a couple of weeks to figure it out. I simply needed to clean the solder itself. I started with soap and water and then I scrubbed it with steel wool. Works great now.
