Postcard / Copper Patinas
From green to ghastly
![A postcard depicting 18 color swatches of various copper patinas.](/issues/20/cabinet_020_postcard_1.jpg)
![The back of the postcard reads “These color swatches catalogue in part the variety of patinas that occur on copper. Patina typically refers to the weathering or aging of a metal surface exposed to air, a natural and inevitable process that produces an elegant simple green. However, the careful application of chemicals can also create a patination in a wide range of ghastly hues beloved by 1980s loft renovators and office lobby designers, including light reddish purple, rich pumpkin orange, and mottled red-and-turquoise.”](/issues/20/cabinet_020_postcard_2.jpg)
