AMERWAY 60/40 SAPPHIRE Solder for Stained Glass (1 LB Spool)

SAPPHIRE-60/40 is 60% tin and the balance lead. A consistent and smooth-flowing solder, 60/40 is the best-selling alloy in the stained glass field. It melts at 372 deg F, and solidifies at 361 deg F. 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.
