Stained Glass Tools
Choose copper foil width, backing and applicator
Compare the glass edge, the appearance through the glass and the tool that feeds the tape.
Allow tape to wrap the glass edge
Width determines how much tape is available to cover the edge and fold onto the two faces. Compare the width against the actual sheet thickness and the seam appearance you want. Check whether your applicator accepts that width.
Check the backing through the glass
Clear pieces may show the adhesive-side color from behind. Compare the black-, silver- and copper-backed variants against the appearance you want for the finished joint. Check the backing description even when two rolls have similar copper faces in photos.
Separate feeding and pressing
An applicator can guide the tape as it is applied, and a burnisher presses the tape against the piece. If you already feed tape by hand and need help only with smoothing, compare a burnishing tool. Check what is supplied before buying a bundle.
