This is a 5 1/2" Mason's Ironstone jug. It is a cream color and has a scalloped edge. The bottom mark is green in color and says "Mason's - Patent Ironstone China - England". This mark was used between 1891 and 1923. It has a couple of very tiny flea bites on the edge. It shows a lot of crazing. It shows as a light and dark colored cream which I believe to be discoloration from the crazing. The price of this jug reflects the problems noted. Please email me with any questions.
