The Cyan and Copper Aurora Borealis pattern washes the coating in soft broad bands that drift like curtains of light across the glass, with no hard edges between the cyan and copper zones. This version carries the pattern over a Bullseye clear, white and black streaky base, so milky white and dark streaks weave under the coating and add their own movement.
As the light angle changes, the coating slides between a cool cyan and a warm copper, the two colors trading places across the curtain bands. The streaky base shifts the way the coating catches, brightening over the white and deepening over the black streaks.
Results depend on your kiln and process, so test a small piece first.

Working Notes
Firing Guidelines and Helpful Tips
Dichroic results vary by kiln, firing schedule, base glass, capping, layering, and coating orientation. These are guidelines, not guarantees. Follow the glass and coating manufacturer's guidance, and test a small piece first when the final look matters.
- Coating side orientation and clear capping can each change the final look, so test first when the result matters.
- Appearance may vary after firing, and the metallic color shift can read differently by viewing angle and lighting.
- Cut and handle the coated surface with care.
What is CBS Dichroic glass?
Dichroic glass is known for showing different colors depending on light and viewing angle. Ancient examples include the Roman Lycurgus Cup, whose color shift came from tiny gold and silver particles within the glass. Modern art dichroic glass uses a different thin-film coating approach: very thin metal or metal-oxide layers on the glass surface reflect some wavelengths of light while allowing others to pass through. CBS Dichroic glass applies this coating over a base glass, and the coating is on one side only.
Is this COE90?
This is COE90.
What base glass is it on?
It is on a Bullseye base.
What sizes are available?

Should I test before firing?
Yes. Dichroic results vary by kiln and setup, so test a small piece first when the final look matters.
Can I cap dichroic glass with clear glass?
Many artists cap dichroic glass with clear, and capping can change the final look. Test first to confirm the result you want.
