Both were saucers that – together with four tea bowls and the teapot – brings the number of known pieces to seven (not six as stated in your article).
The primary pattern on the teapot featuring the cranes by a river is illustrated on a saucer in the final section of my newly published book (cover below), British Blue and White Porcelain Saucers 1745-1795 *.
Among 480 different blue and white designs, the book features the two Bartlam pieces. It relates the story of how I acquired them as Isleworth and subsequently found out that they were important American pieces, as well as summarising the exciting discovery of Bartlam’s porcelain at Cain Hoy, South Carolina.
Both saucers are now in US collections.
