This is an early Mason's Ironstone pottery small rectangular platter, hand painted in the very decorative basket Japan pattern, produced by the Mason's factory at Lane Delph, Staffordshire, England, in the George 111rd period, circa 1813-1820.
 
The plate is rectangular with canted corners and a notched indented rim.
 
The platter is hand decorated in one of Mason's most beautiful chinoiserie patterns, called Basket Japan, which is also one of their most collected and striking patterns. The pattern is boldly hand painted, over-glaze in enamels of cobalt blue and burnt orange all in varying shades, possibly over an under-glaze printed outline. This pattern is illustrated on page 103 of Mason's pattern book published by The Mason's Collectors' Club.
 
The base has the single line impressed mark "MASONS PATENT IRONSTONE CHINA" which is recorded as being one of the earliest impressed factory marks indicating a date of circa 1813-1820 as ironstone was only produced by them from 1813, which is late George 111 period.
 
This plate exhibits the free flowing quality and boldness of the hand painting that is seen on the early Mason's pieces.
