All copper foil is adhesive backed with a release liner
Copper foil tips
-
When using glass that you can see through, choose a foil with the same color backing as the patina you intend to use. Example: Black Back for Black Patina.
-
Foil comes in different thickness. 1 mil is good for inside curves because it folds easily. 1.5 mil is good for raw non smoothed edges. It’s harder to tear, so it holds up to sharp edges better. We sell 1.5 mil foil unless otherwise noted.
-
Burnish your foil down tightly, leaving no air bubbles. This prevents flux from seeping under the foil.
-
If you have to put a project away when it’s partially foiled, tape a small piece of foil to it so you use the same size later.
-
Cover your project to prevent oxidation.
-
Store opened copper foil in a zipper bag to help prevent oxidation
