Seagrove Red is an earthenware glaze which gets its brilliant red color from cadmium. For this reason, the glaze is strictly decorative. Reds can also be achieved by lead, chrome, or copper. Cadmium and lead, however, give the most vibrant red colors. This glaze is very difficult and requires strict application and firing techniques. To intensify the color, McCanless Pottery uses a red, iron-rich earthenware clay. The complex forms thrown for these pieces add to the beauty of the glaze. McCanless Pottery uses the name Seagrove Red because of the glaze's rich tradition, throughout the generations, in the Seagrove area.
