Amerway 60/40 Solid Core Solder for Stained Glass 1 Pound
1 pound spool of Amerway Solder 60/40 which means 60% tin and 40% lead.   A consistent and smooth flowing solder, 60/40 is the best selling alloy in the stained glass field. It melts at 372F, and solidifies at 361F. The "pasty range" (most solders melt at a higher temperature than they freeze at, the difference between these figures is the pasty range) of 60/40 is smaller than that of 50/50, giving the user a smoother bead.
