Swastika Keramos pottery was introduced by the Owen China Company in 1906. The line has no connection to historical events. It has been rumored that Swastika Keramos was developed by John Lessell. Lessell is best known for development of Weller LaSa.
The Swastika Keramos line was produced only for a short period of time. Most believe the production ended by 1908. Most examples of Swastika Keramos are marked with a raised seal mark similar to the Roseville Rozane wafer mark.
