During the 19th century, there was a craze for work by the Renaissance potter Bernard Palissy (1510-1590) in both France and Portugal, inspiring interest in the originals, and the development of revival pieces in the same style.

In Portugal, manufacturing was concentrated in the town of Caldas da Rainha, where in the 1850s Manuel Cipriano Gomes Mafra (1830-1905) began to adapt Palissy’s style in a strikingly different direction quite unlike that of his French counterparts. He incorporated the technique of pressing wet clay through a sieve to create the effect of moss as his principal background and expanded the subject matter, introducing narrative elements and extending the nature morte metaphor. This plate with fish and sea urchin is a good example of Mafra’s musgo (moss) technique
