Hello Catherine,

    I have done a lot of gold to silver and other mixed metals soldering.
    The main thing you need to be careful of is not to overheat when
    soldering gold to silver. That is why you got a mess on your first
    try. Getting your reflexes down to know when to back off with the
    torch is most important. What will happen is that as the solder
    dissolves into the silver and gold in a liquid state that it causes
    the two metals to mix together into a fairly lower melting new alloy
    that behaves like solder and may actually melt at a lower temp than
    the solder you start with. This can turn a nice joint into a glob in
    a brief moment. The result will look like you used way too much
    solder and the components sink into each other. 

    I have heard people say that you should only use gold solder when
    joining silver to gold, but I never do. I use an easy or extra easy
    silver solder. You can use the same flux for either silver or gold
    solder.
