The Sinceny manufactory (sometimes St. Cenis) was a French producer of ceramics, especially faience, located in the city of Sinceny, Picardy, France.
The Sinceny manufactory was founded in 1713, when potters from Rouen and before from Nevers* moved there to establish their own venture. As a consequence, Sinceny ware copied Rouen ceramics to the point of being sometimes indistinguishable from it.
