1/4" Black Back Copper Foil Tape - High Conductivity Adhesive for Electrical Repairs, EMI Shielding, Stained Glass & DIY Crafts - Perfect for Home Improvement and Art Projects

It has very good adhesion, but I was making a consigned piece, with end result in black patina. I was a bit disappointed in the amount of copper speckles on the blacked side of the tape. The end result is that likely no one will notice but me. Other black backed copper foil products I've used, have very black backed foil and adhere nicely as well. Best price, earliest delivery, and I'll try to ignore the speckles.At 1.25 mill thickness it is easy to work with but adds some strength to you projects. The adhesive also sticks well to the glass that I find lacks in other products.Great tack. Sticks well to glass. Has a great stretch on inside curves so it doesn't split.Exactly what I was looking for, local stained glass shopmclosedGood size and adhesion, but had to knock down the rating due to lots of thready edges that made application more difficult. Other brands I've used seemed to have better quality control.Excellent copper foil. Excellent service.Good service. Great product.
