The glass displayed here is Bullseye Black Fractures with Black Streamers on clear, where broken black flakes and slender streamer threads scatter across a transparent base. The dark graphic web floats in clear glass, letting light pass through the open spaces between the marks.
The Rainbow 2 coating spreads the full spectrum over that ground, sweeping red through gold, green, and into blue and violet. Where the clear shows through, the rainbow shifts freely between the black fractures, the whole spectrum sliding along as the viewing angle changes.
Test a small piece first because the layered fractures and rainbow sweep change with kiln and setup.

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?
Available sizes: 2"x4", 4"x4", Quarter Sheet.
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.
