The product is referenced by the copper and verdigris on the ripples and ridges. Due to subtly varying verdigris (green patina), each piece is unique, a sculpture of contrasting color and texture. Designer Lisa Smith scallops the rim in a symmetrical pattern and emphasizes the scallops' rhythm with ridged, wave-like verdigris sloping down to the bowl's flat bottom. A smooth band at the top glows with copper's pure warmth.
