Dichroic Coated Copper Foil

CBS (Coatings by Sandberg) has developed a new product called Dichroic Coated Copper Foil.

Instead of placing the Dichroic coating on glass, copper foil is placed inside the chamber and coated with about 4 layers.

There are many benefits of this new form of using Dichroic.

It is simple to use, about half the cost of purchasing Dichroic glass and can be placed on any COE of glass.

This material is designed to come off of the coated foil, and sometimes in the shipping process, the Dichroic will start to release from the copper carrier.

When purchased it come in a static free 6” by 12” bag.

It can be purchased in various rainbow hues.

Dragging the sealed bag over the edge of a table, or crinkling the bag in your hands will help to release the Dichroic.

After releasing the copper, open the bag and the material should loosely fall to the bottom in chunks or flakes.

Store any unused Dichroic inside the static free bag.

Experimenting with these flakes is highly recommended.

Fun ways to use the Dichroic Coated Copper Foil:


  • Start with a blank base of glass.
  • Reach into the static free bag and grasp some of the flakes.
  • Scatter these pieces across the glass.
  • Use a brush or finger to move the material around to your liking.
  • Cap with clear glass.
  • Fire.
  • Pulverizing and Screening

  • Use either the static-free bag or static-free container to grind down the Dichroic with your finger.
  • Place a blank piece of glass on your kiln shelf.
  • Using a dry wall sand paper screen begin pouring the pulverized Dichroic onto the screen.
  • Tapping the screen will enable more of the particles to fall through the openings.
  • You can also use your finger to move the Dichroic around on the screen causing more of the fine particles to fall.
  • Once you achieve your desired look, cap the piece with some clear glass.
  • Fire.
  • Firing on a Kiln Shelf

  • Place a piece of clear glass on the kiln shelf and trace around the edges using a pencil.
  • This will enable you to only place the Dichroic particles in your designated area.
  • Sprinkle the Dichroic particles in the outlined area.
  • Cover the area with the original clear glass.
  • Fire.
  • Since Dichroic will not stick to Dichroic when fired, you might find that some of the Dichroic didn’t adhere to the glass and can be easily removed.
