The wavy pie-crust decoration surrounding the aperture I have seen on a number of pots from Rye and the patterns of the iron oxide particles displayed on the surface of this pot are very similar to others I have seen from the Rye pottery’s. This particular example is elaborately decorated with various waves and squiggles and dots and there are some losses to these areas of slip.
Unfortunately it is lacking its handle but it is initialled P.O. and dated.
