Overlays are often used in stained glass projects to create details, add texture and whimsy, which would normally be impossible or at the least, extremely time consuming to create using pieces of cut glass. They and allow the artist to customize a specific piece their client’s needs.
We recommend tinning/texturing the overlay on the backing sheet that it comes on. For best results use you soldering iron on a low setting. Don’t use a lot of flux when soldering or tinning overlays. Excess flux can seep under the overlay and cause the adhesive to lift.
The overlays can also be placed on your glass prior to tinning/texturing them. We do not recommend doing this unless you have experience soldering and using overlays. It’s too easy to heat shock your glass if you are not experienced using them.
