Monmouth Pottery: Illinois Stoneware and Art Pottery

Monmouth Pottery Company, established in 1893 in Monmouth, Illinois, was a significant producer of utilitarian stoneware and later art pottery. The company merged with several other western Illinois potteries in 1906 to form the Western Stoneware Company, which continued operations at the Monmouth facility. Collectors today seek both the pre-merger Monmouth Pottery wares and the Western Stoneware products made at the same location, particularly the popular maple leaf mark stoneware and the later artware lines.

History and Development

  • Monmouth Pottery Co. (1893-1906): Utilitarian stoneware, crocks, jugs, and churns
  • Western Stoneware Co. (1906-1985): Merger of six Illinois potteries including Monmouth; continued stoneware production
  • Art pottery period: Introduced Monmouth artware lines including vases, planters, and decorative pieces
  • Later production: Gradually shifted to more commercial products; operations ceased in 1985

The maple leaf mark became the iconic symbol of Western Stoneware/Monmouth production and is the mark most collectors associate with the name.

Collecting Tips

Monmouth/Western Stoneware appeals primarily to Midwest Americana collectors and stoneware enthusiasts. Cobalt-decorated pieces command the strongest interest, particularly those with advertising stencils for local merchants, which have crossover appeal to advertising collectors. The maple leaf mark is iconic and immediately recognizable. Large-format pieces like water coolers and five-gallon crocks have strong decorative appeal. Art pottery lines are generally more affordable and less collected than the stoneware, offering opportunity for collectors willing to explore this secondary market. Condition is more forgiving in stoneware collecting than in porcelain, but serious structural damage still substantially reduces value.
