Teco

Many pieces were made with matte green glaze, some with a metallic black overglaze, but other colors such as brown, yellow, blue, pink and maroon were also made. These items are considered to be part of the arts and crafts movement and are highly regarded by art pottery enthusiasts. Most collectors are attracted to Teco for the unique and creative shapes of the pieces, especially those with geometric features rather than the color of the glaze, according to JustArtPottery.com.
