Established by the Marchese Ginori in 1737 with help from German workmen with experience in porcelain making (ie originating in Meissen, the first true porcelain maker in Europe), this factory near Florence made unique forms in a distinct grey paste, often disguised under a thick white glazed achieved by using tin oxide. Their wares are rare and keenly sought after.
The coffee pot is a particularly interesting piece, having the flamboyant birds-head spout.
Circa 1765, more photos and description here.
The plate has a version of the 'Tulip' pattern, based loosely on a Chinese Export pattern of the early 18th century. Circa 1790, more info & pictures here.
There are a couple of interesting cup s & saucers also - this Imari style one with a fenced garden, Circa 1760 - more photos & info -
...and another with a very unusual pattern which is loosely Neo-Classical - Circa 1760 - more photos & info here -
And finally, a snuff box, left undecorated, with a whimsical depiction of an embracing old (?) couple - Circa 1780 - more photos & info here.
