Etched Black Hole Pattern centers a dark void surrounded by radiating zentangle bands — fish-scale arcs, checkerboard ribbons, oval drops, and fine wave linework fan outward from the core. The result is bold, line-forward etched dichroic glass. This pattern is freestyle and non-repeating.
A darker base works best — the etched negative space at the central hole and radiating rays frames the dichroic shimmer of the surrounding zentangle linework with strong graphic contrast. Iridescent bases also work for projects that want softer, more diffused contrast.
Best for statement focal cuts, pendant centerpieces, and one-off panel projects driven by a single bold composition with a strong central anchor.

Working Notes
Firing schedule: use the firing guidance for the base glass you select and adjust for your kiln, project thickness, layering, and desired finish. Firing schedules are guidelines, not guarantees. When appearance or compatibility is important, test a small piece before using the glass in a larger project.
Cap or no cap: Many artists use a clear cap to help protect the dichroic surface and create a richer, glassier look. Uncapped and tack-fused approaches may also be used depending on the project, firing style, and desired finish. Test a small piece first when the final appearance is important.
Cutting: score coating-side-down on the smooth back. Standard wheel, standard oil, standard pressure. Cut, run, separate as usual.
Anneal: Anneal according to the base glass manufacturer’s guidance for the total thickness and size of your project. The dichroic coating does not replace or reduce normal annealing requirements.
Devit risk: Devitrification risk depends on the base glass, firing temperature, kiln conditions, and surface exposure. A clear cap or appropriate glass-fusing practices may help protect the surface, especially when the base glass is prone to devit. Avoid direct flame unless you have tested the specific glass and coating combination.
Frequently Asked Questions
What is freestyle etched dichroic glass?
Freestyle etched dichroic is a dichroic-coated glass sheet where selected areas of the coating have been removed to leave a pattern. The remaining coating reflects and transmits light dichroically; the etched-through areas are clear to the base glass underneath. The coating is on one side of the sheet only. The pattern is intended for kiln-forming when used with compatible glass and appropriate firing practices.
What COE is available for Etched Black Hole Pattern?
This pattern is available in COE90 or COE96 — select your preferred COE at order via the dropdown. The etched dichroic coating itself is COE-neutral; compatibility is set entirely by the base glass you select. Do not mix COE90 and COE96 in the same fused-glass project; incompatible expansion rates can cause cracking during cooling or later stress.
Which side of Etched Black Hole Pattern is the dichroic coating on?
The coating is on the shinier, more reflective side. Hold the sheet up to a light: the side showing the pattern crisply with no shadow offset is the coated side. Cut coating-side-down to keep the pattern intact — pressure on the base glass, score line on the smooth back. Standard scoring oil and pressure; no special wheel needed.
Which base works best with this pattern?
The Etched Black Hole Pattern has a strong central void and open radiating rays — a darker base reveals the etched negative space and frames the surrounding dichroic linework with high graphic contrast. Iridescent bases also work for a softer, more diffused look. Final pairing is yours to pick from the base drop-down.
