Pâte-sur-pâte is a French term meaning "paste on paste". It is a method of porcelain decoration in which a relief design is created on an unfired, unglazed body by applying successive layers of white slip (liquid clay) with a brush. The effect is somewhat similar to other types of relief decoration (sprigging). However, unlike Jasperware, for example, a mould is not normally used, and the ceramic artist is able to achieve translucency.
The development of pâte-sur-pâte dates back to 1850 in France, and an accident that occurred at the Manufacture nationale de Sèvres. The company was trying to reproduce a decorative technique from a Chinese vase, but misinterpreting the vase, the experiment took them along a different path from the Chinese potter. They perfected what became known as pâte-sur-pâte.
Another notable maker was Marc-Louis Solon, who perfected the technique and was for most of his working life the leading exponent of the technique. Solon was born in France in 1835 and from an early age developed a considerable talent for art. Some of Solon's work later fell to the attention of the art director of Sèvres and he was soon after employed as a ceramic artist and designer. He was tasked along with H Regnault and Gelly to work upon the pâte-sur-pâte process which was still only at the trial stage. Sèvres reached a high level of refinement of their pottery. Praising the facilities of the day, Solon commented that "We were never limited as to time and cost", a luxury in any industry. Solon also began to produce pieces of pâte-sur-pâte in his own time under the name Miles, said to be based on his initials M L S. There are a number of these in the Victoria and Albert Museum's collection, as well as in the collection of the former Minton Museum.
The Franco-Prussian War of 1870 led Solon to flee his native country and seek refuge in England, where he established contact with Colin Minton Campbell of Mintons Ltd, Staffordshire. Mintons had a history of employing foreign artists. Its first Frenchman arrived in 1848, the art director Léon Arnoux, followed by other French makers such as the sculptor Albert-Ernest Carrier-Belleuse, so Solon was joining a small continental community when he settled in Staffordshire and married Arnoux's daughter. The Solons brought up a large family at The Villas near the Mintons factory. To meet the demand for pâte-sur-pâte he was assigned English apprentices including Frederick Alfred Rhead. There ensued a golden age of pâte-sur-pâte in Stoke-on-Trent stretching into the early years of the 20th century.
