Product Information

Bullseye Copper Foil is fantastic for adding decorative elements to the surface or interior of your fused works. As Copper will react with a number of glasses, it's important to avoid contamination by keeping copper from touching the kiln shelf, better still, use a separate shelf for fusing with metals.

  • Can be cut with scissors and placed between layers of glass.

  • It will change colour if exposed to oxygen whilst firing and a variety of results can be achieved.

  • Also available, Gold or Silver Foils in 100 gauge.

  • 25.4 microns thick

Copper foil fish and copper wire are used in this fused glass piece:

Copper foil can create some exciting and unpredictable reactions with some sulphur-bearing glasses such as French Vanilla.  This image is from one of our 'Reactive Inclusions' courses:

I’ve found if you sandwich the copper foil between a folded sheet of paper and then punch the design out it stops the foil from sticking to the punch.

Loving this product, great value for the money, a sheet goes a long way. I read up on this and found that Boric acid stops the copper oxidising and keeps the copper keeps its original colour after firing.
I tested by
1) Sprinkling the Boric acid powder over foil coated in two places with glastac and shaking off the excess - although the copper kept its colour the test sample had a rough edge where residues/ gasses had escaped. The entire piece of copper had kept its original colour, not just the area covered in boric acid.
2) Mixing boric acid with glastac and applying thinly with a paintbrush in a line, this produced a pleasing result with the painted line keeping the natural colour of the copper and the unpainted area turning red.
A little boric acid seems to go a long way, it dries quite quickly after application.

I made a house number plaque cutting out the number and a chestnut leaf in this copper. I used opal white for the backing capped with clear, the colours are outstanding, exactly what I was hoping for with autumn russet colours on the leaf. I should get my post now!

I have used this for along time if you smooth it out with roller both sides the finish is lovely.
It' fires lovely shades of blues reds like oil on water .It's a great price for what it can achieve .Works well with large punches

Used this to create some pendants. I used black opal on the bottom, then a cut heart in copper foil and capped it with clear. The results were very nice. The copper changed into a very nice warm dark rose/purply red. I used scissors to cut the copper, but am trying the next batch with punchers (for a cleaner cut).

Purchased two sheets of this with my last order. arrived in good condition, well packaged. cant wait to use it. i normally use paper punches to cut out shapes to fuse between glass.

Great stuff, can be cut with scissors or a craft knife for more intricate effects. Maintaining the copper colour (if desired) is a bit more problematic. Tends to go a nice dark red colour.

I love copper inclusions and I really like that the results are unpredictable so sometime it may be blue, other times red but my favourite is when the copper turns purply sometimes.
