This solder is composed of 50% tin and 50% lead. 50/50 solder will produce a much "flatter" bead than 60/40. Because of its higher melting point, 50/50 solder is often used on the back (or inside) of a stained glass project to protect against "melt through" when soldering the front. Because it spreads and flattens out, 50/50 solder is often used when soldering lead came joints.
Start stained glass project by first applying flux to the foiled glass. Flux allows solder to bond to the foil. Next, drop a bead of molten solder at every joint. This is called tack soldering and it will hold all the pieces in place while you apply a bead of solder on each seam.
Move the soldering iron and solder simultaneously along the foiled seam, to produce in a bead that rises above the glass surface. Spending too much time in one area or resting soldering iron tip on the glass will cause the glass to crack. It is best to return later to even out and refine solder lines.
- Too much flux can cause pits to appear in the solder bead.
- Too little flux will result in some portion of the foil remaining visible.
- Lumpy seams are caused by soldering iron melting the solder at a temperature that is too low.
- A flat bead means that more solder is needed.
