Translucent porcelain, speckled brown interior is from Costa Rican Accretionary Prism and area inside surrounding blue center is from Mid-Atlantic Ridge, as is the exterior glaze -- Earth crust slurry spread thinly on porcelain -- when conditions are right -- makes a smooth lustrous translucent glaze (so different from the same materials thicker on stoneware!). Rim and foot are glaze assembled from refined materials. |
