A Rainbow 1 dichroic coating sits on this Wissmach Thin Black Aerolite COE90 glass. Against the black base, the multicolor coating appears as bright bands of color across a dark surface, with the black blocking light from behind.
The Aerolite texture scatters the coating into a fine irregular pattern, so the mix of hues catches at varied points as the angle changes. The metallic shift varies by angle and lighting, and appearance may change after firing.
Test a piece first to see the color spread against the black.

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.
Frequently Asked Questions
What is CBS Dichroic glass?
Dichroic glass has ancient roots, including the Roman Lycurgus Cup. Modern dichroic glass was advanced through NASA era vacuum deposition work, where ultra thin metal coatings were applied to transparent surfaces for optical protection. Today, dichroic glass uses thin metal oxide layers on the glass surface to create a metallic color that shifts with light and viewing angle. CBS Dichroic glass applies this coating over a base glass, and the coating is on one side only.
