Hey Guys, I checked the histogram...it doesn't look good. I'm assuming the graph for the black bars has to be in the green on the left and the graph for the white card needs to be in the green on the right?? Anyways, I can't find a "GS4 pot" I looke

arnold: I did not say that Sn100 dissolved copper faster. The graph of dissolution rates [from the link above] shows that Sn100 dissolves copper slower than many of the other solders.
