Barro negro is the burnished black pottery of San Bartolo Coyotepec, Oaxaca, where iron-rich clay is polished with quartz before firing and then smothered in a low-oxygen kiln until it turns deep metallic black. The result is a black-on-black artifact: glossy graphite surfaces, matte-black shadow, and a faint silvery-pewter burnish along every edge.

This design system honors that artifact. It is definitively dark, never cream, with no chromatic primary — only the contrast of gloss against matte and the one light that exists in the object: a silvery sheen catching the curve.
