From paying attention to wings, I became interested in feather structures. How crazy, exactly, is the idea of a glass feather? But feathers, like glass, have both delicacy and strength. A plume, by the way, is a technical heraldic term for a three-feather structure.
Plume is a wall piece in fused and slumped glass with sandblast and dichroic details, mounted on fired stainless steel.
