Etched Piazza Pattern layers zentangle mandalas, fine-line sunbursts, fish-scale fields, and woven ribbon bands between the circular medallions. The etched dichroic glass is line-forward, with dense white linework holding the coating over deeply etched negative space. This pattern is freestyle and non-repeating.
A dark base works best — the open etched areas reveal the base while the dichroic shimmer holds in the remaining linework, framed against the dark field. Iridescent bases also work, softening the contrast and giving the pattern a quieter finish.
Best for focal cuts, statement panels, and jewelry built around a single layered linework field that anchors the composition.

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 Piazza 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 Piazza 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.
Q4: Which base works best with this pattern?
The dense linework leaves substantial etched-away negative space, so a darker base frames the dichroic shimmer held in the remaining lines. Iridescent bases also work and soften the contrast. Final pairing is yours to pick from the base drop-down.
