Zark Pottery was produced by the Ozark Pottery Company in St. Louis. Zark Pottery production started around 1907. Production of Zark ceased sometime in 1910.
During its brief existence, Zark produced both decorated and undecorated art pottery. Decorated examples of Zark have been founded in both slip decorated and carved relief. Examples are typically marked with either an incised or stamped Zark. In addition, some pieces are artist initialed.
