North Dakota School of Mines: University Art Pottery (1910-1963)
North Dakota School of Mines pottery was produced at the ceramics department of the University of North Dakota (originally the North Dakota School of Mines) in Grand Forks from 1910 to 1963. Under the direction of Margaret Kelly Cable, who led the program from 1910 until her retirement in 1949, students created art pottery using local North Dakota clays. The pottery is celebrated for its distinctive carved and painted decorations featuring regional themes -- wheat sheaves, buffalo, prairie roses, covered wagons, Native American motifs, and Viking ships reflecting the state's Scandinavian heritage.

Condition Factors
- Carved decoration must be crisp and well-defined; worn or rubbed carving reduces value significantly
- Chips on rims and bases are common on student-made pottery and reduce value by 20-40%
- Glaze fit issues (crazing, crawling) vary by student; some technical imperfections are accepted as part of the educational nature of the work
- Pieces by identified Cable-era students bring premiums over anonymous examples
- Original surface condition is essential; do not attempt to clean or refinish
Collecting Tips
- Margaret Cable's personal influence makes the 1910-1949 period the most desirable; her guidance ensured consistent artistic quality
- Regional themed pieces (buffalo, covered wagons, wheat) are the most sought after and bring the highest prices
- Student identity matters when known; some students went on to notable ceramic careers
- The pottery has strong regional appeal in the Dakotas and Upper Midwest, where it appears most frequently at auction
- Pieces using the carved-through-slip technique are generally more valuable than painted decoration
- The university's archives may hold records of student work that can help document specific pieces
