Art pottery production was at an all-time high during the late 19th and early 20th centuries. At this time over one hundred companies and artisans were producing individually designed and often decorated pottery which served both utilitarian and aesthetic purposes. Artists often moved from company to company, some forming their own firms.
Condition, quality of design, beauty in glazes, and maker are the keys in buying art pottery. This category covers companies not found elsewhere in the guide.
