Painted c.1800 en camaieu in dark green with Georgian buildings, one titled Butterley Hall, two were signed for Sarah Jessop.
As well as a talented decorator, she was the wife of William Jessop, the noted civil engineer best known for his work on canals, harbours and the early railways. He was co-founder of the Butterley Iron Works, Derbyshire.
The inherent rarity of large Pinxton wares, coupled with this connection to the industrial history of Derbyshire, led to an impressive bid of £7000 at the auction on January 30-31.
The largest pot at 10in (25cm) across had a number of cracks but the two smaller pots and covers were in better condition.
