Fused Glass Metal Foil Firing Techniques

Gold, silver and copper metal foils can be cut into different shapes and added to fused glass artwork. Metal foil adds dimension and sparkle to fused glass designs. Adding gold or silver to fused glass is a way to create jewellery and household items with precious metals without breaking the bank.

Choice of Metal Foil

Metal foil comes in many choices for fused glass including copper, gold and silver. Each metal is a different colour and will give a different look. Pure gold and pure silver will not oxidise when fired and will retain their colour. Copper is a far less expensive material than either silver or gold, but copper usually oxidises when the fused glass is fired in a kiln; the final colour for copper foil is less predictable than either silver or gold foil.


Metal foil can be cut with scissors, a craft knife or craft punch and sandwiched in between fused glass. When metal is sandwiched in glass it is called "an inclusion." Place a piece of fused glass on the kiln shelf. Put the metal foil on the glass. Stack a piece of clear or transparent glass on top of the foil. Fire in a glass fusing kiln. After firing, the encased metal foil will look as though the metal is floating in the completed fused glass.


Metal foil can be affixed to the surface of fused glass and then fired. Use glass fusing glue to stick the foil to the surface of the glass. Use a craft stick, the back of a spoon or a burnisher to push all the air bubbles and liquid out from under the foil. Allow the glue to dry and then fire the foil covered fused glass in a glass fusing kiln.


Save scraps of metal foil. Cut the scraps into small pieces and use the small pieces in fused glass projects for interesting effects. Scraps can be sprinkled on the surface of fused glass or sandwiched between layers of glass. Scraps will create small bursts of colour and give a completely different look from larger cut or burnished pieces.
