Little is known about the Eureka pottery. The pottery itself was located in Trenton NJ and was in production for only four years starting in 1883. Their majolica output is dated to the first two years of that period. The legacy that the pottery left us however has lasted well over 120 years.
The company made a number of Japonesque designs in that brief time but the design for which they are best known is their "Fan" design.
These fan plates are relatively easy to find though pieces with intense color will command higher prices. The hollowware pieces, particularly the tea set, are much harder to find and will command a premium.
