History

It began with salt glaze and Albany slip decorated in cobalt, then moved to Bristol glaze with stenciled and stamped marks. In 1906 it became Plant 1 and the head office of the new Western Stoneware Co., which kept its maple leaf trademark.

Dating clues

  • By 1902 most Monmouth wares carried the maple leaf; after 1906 the leaf reads 'Western Stoneware Co.' with a plant number.
  • Salt-glazed pieces with freehand cobalt are from the early years, before the change to Bristol glaze.

Look-alikes and reproductions

  • Western Stoneware Co. maple leaf marks (1906 on).

Where sources disagree: Western Stoneware's own history dates Monmouth Pottery to 1892; the Blue & White Pottery Club and WorthPoint say it began production in 1894.
