Tray plates in two different sizes, each polished to a velvety sheen. The effect is unique to barro negro pottery, which is made through a highly sensitive process using Oaxacan clay that turns black at increased temperatures. Only a few artisans exist who are truly adept in these techniques and the clay cannot be found anywhere else in the world. Small measures 7.5 x 5.5 inches. Large measures 10.5 x 7.5 inches. Designed in Mexico City, made in Oaxaca.
