A very rare Caughley tea bowl in the 'Trench Mortar' pattern, circa 1790-98, unmarked, 8cm diameter (hairline) Provenance: Wright Collection no.582 purchased 1998 from S. Millington. Literature: This is the only piece of Caughley known to demonstrate this pattern, otherwise better known on hard-paste porcelain from the New Hall factory. A pull from a copper plate has recently been found in the Coalport Rag Book, confirming a Shropshire origin. The Rag Book is held at the Wedgwood Museum and contains patterns from both the Caughley and Coalport factories. The paste of this bowl together with the nature of the potting and the foot-rim suggest a Caughley rather than Coalport origin, although some remain sceptical of this attribution.' The Caughley Society, Caughley Blue and White Patterns, p.183 has a full page illustration and discussion of this tea bowl.
