Etched Carbonation Pattern packs concentric rings, solid discs, and scattered dots together, with thin lines linking many of the circles. This etched dichroic glass is bold and graphic, built from crisp circular edges and a wide range of ring sizes. This pattern is freestyle and non-repeating.
A darker base suits this high-contrast pattern best: the bold etched circles open onto the dark field and frame the remaining dichroic coating where the shimmer concentrates. Iridescent bases also work, softening the contrast between motif and ground.
Best for jewelry, cabochons, and focal cuts, where the busy circle work anchors a piece on its own.

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 Carbonation 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 Carbonation 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?
This is a high-contrast pattern of bold etched circles, so a darker base frames it well — the etched negative space stays clean against a dark field and the remaining dichroic coating stands out. Iridescent bases also pair nicely for softer contrast. Final pairing is yours to pick from the base drop-down.
