Help identify the maker of this pottery jug.
Unsigned. Large heavy stoneware jug with heavy shiny black drip glaze. Weight is 3 3/4lbs. Stands 11 1/2" and is approx. 6 1/2" in diameter
at the widest part. In excellent condition. Several minor glaze skips and other tiny imperfections from the making. There is one 1cm roundish scratched area on the most prominent area of the body. I believe this shows in an image, from the flash, otherwise not seen easily. Any information on the origin and potter would be greatly appreciated. Thanks! NothingDoing
