The marks, by date

Each mark’s wording is written out as a transcription: the words and line breaks, not a picture of the mark. Where a source describes a mark instead of quoting it, the description is shown in italics.

History

Around 1909 it introduced its red wing trademark, and stamped ovals and printed decorations gradually replaced hand work. The company renamed itself Red Wing Potteries, Inc. in 1936 as it moved toward dinnerware and art pottery; stoneware ended in 1947 and the plant closed during a strike in 1967.

Dating clues

  • A red wing on the side points to 1909 or later.
  • Handled jars carry patent wording for bolted-on handles from December 1915 until stoneware ended in 1947.
  • Machine-turning of large ware ended around 1917.

Look-alikes and reproductions

  • Union Stoneware Co. ovals (c. 1900–1906), which lack 'RED WING' in the company name.

Other names on the marks

Red Wing Potteries, Inc. (from 1936); RWUSCo.

Marks help identify a maker and a date range, but they can’t prove a piece is genuine. Reproductions and later reissues can carry old marks. This entry isn’t an appraisal.
