EDCO 3/16-Inch Black-Backed Copper Foil
A narrow black-backed foil that avoids a bright copper line showing through transparent glass after dark patina.

Black-backed foil is a visual choice. On clear or cathedral glass with black patina, the dark adhesive side is less conspicuous than copper where the foil can be seen through the glass.
Reasons to choose it
- Clear glass with a dark finished seam
- 3/16 in width
- Black backing
Consider before buying
- Match backing colour to the finish
- Use only on clean dry edges
- Choose 7/32-inch foil for thicker glass or a wider solder line, and copper-backed foil when the finished seams will stay copper-toned.

What ownership is actually like
Centre and burnish it carefully; backing colour cannot hide an uneven wrap. Store the roll sealed and dry to protect the adhesive.
Who it suits
This is a strong shortlist candidate for clear glass with a dark finished seam. The useful question is whether that describes most of your work, not merely one future project.
When another tool makes more sense
Choose 7/32-inch foil for thicker glass or a wider solder line, and copper-backed foil when the finished seams will stay copper-toned.
