Teco is the mark used on the art pottery line made by the American Terra Cotta and Ceramic Company of Terra Cotta and Chicago, Illinois. The company was an offshoot of the firm founded by William D. Gates in 1881. The Teco line was first made in 1885 but was not sold commercially until 1902. It continued in production until 1922. Over 500 designs were made in a variety of colors, shapes, and glazes. The company closed in 1930. The name Teco comes from the "te" in terra and "co" in cotta.
