Like cutouts from a stone wall, the colored design surfaces stand out from the background - both visually and spatially.
The three design elements stand out about 10mm from the background.
I also chose Bullseye's satin iridescent glass for this piece. The gradient consists of Bullseye glass red 1122-31F, orange 1125-31Fi, warm yellow 1320-31Fi, light amber 1437-31Fi and colorless 1101-31Fi. The background glass is the 1101-46Fi with Accordian structure.
With this glasswork it is very important that you use very narrow copper foil for the small rectangles - otherwise the design will be lost.
