Eric Norstad was an American potter and architect who worked primarily in the Bay Area. In 1962 he opened Norstad Pottery. Norstad credits artists Peter Voulkos, Bernard Leach, and his parents as influences, as well as clean, functional Scandinavian design of the 1930s, 1940s and 1950s. The stoneware clay that Norstad Pottery mixed was a combination of Kentucky ball clay, California fire clay, and grog- a sand like material. When fired the pieces vitrified into an extremely hard, dense, non-porous material. Norstad pots were most noted by their distinctive glazes, often with markings in a Japanese style Sumi-e brushwork. In earlier pieces relief features or decorated carvings were added to the pots.
