Ritas Bazaar has dated this Worcester Porcelain Teacup Saucer to the Georgian era.

The decoration is fully hand-painted, with excellent preservation of enamels. The porcelain body is dense and cool white, finished with a smooth transparent glaze typical of Worcester’s finest early 19th-century output. The saucer’s softly undulating rim complements the cup, creating a refined ensemble.

The FBB mark dates the piece securely to 1807–1813, the firm’s most accomplished period, when Flight, Barr & Barr held royal patronage as suppliers to King George III.
This tea pair retains its original label from the 2004 Loan Exhibition curated by Dr G. Girton, confirming its exhibition at Stockspring Antiques, London, and later at The Museum of Worcester Porcelain.
