Please note that on the middle shelf are three examples of William Greatbatch's China glaze production which can be tightly dated to the 1775-1782 period. This a period of innovation and experimentation with glaze formulae; each plate reflects significant glazing differences.
Above the Greatbatch examples are other China glaze examples that date to 1800 - 1820.

A selection of China glaze plates, dishes and a few punch bowls and jugs.
These range in date from circa 1775 to the 1820s.
