Spode Dessert Plates

The bone china formula

During the 18th century a lot of English potters had been striving and competing to discover the industrial secret in the production of fine translucent porcelain. The Plymouth and Bristol factories, and (from 1782-1810) the New Hall (Staffordshire) factory under Champion's patent, have been producing hard paste or accurate porcelain related to Oriental china. Inside artificial or soft-paste porcelain, imitating French creation like Sèvres, silica or ground up flint was applied within the clay to give it strength and translucency. The procedure was made by adding calcined bone to this glassy frit, for example within the productions of Bow China works, Chelsea and Lowestoft, and this was carried on from at least the 1750s onwards. Soapstone porcelains further added steatite, known as French chalk, for example at Worcester and Caughley factories.

The bone porcelains, especially those of Spode, Minton, Davenport and Coalport, eventually established the standards for soft-paste porcelain which have been later (right after 1800) maintained widely. Despite the fact that the Bow, Chelsea, Worcester and Derby factories had, just before Spode, established a proportion of about 40-45 per cent calcined bone inside the formula as normal, it absolutely was Spode who initial abandoned the practice of calcining or fritting the bone-ash with some with the other ingredients, and applied the easy mixture of bone-ash, petuntse (china stone) and china clay, which since his time has formed the technical physique of English porcelain, and to a lot of other parts from the world. A common English paste might be taken as 6 parts bone-ash, 4 components petuntse and 3.5 elements kaolin, all finely ground together. This is essentially the same as accurate porcelain but with the addition of a large proportion of bone-ash.

Josiah Spode I effectively finalized the formula, and appears to have been doing so between 1789 and 1793. It remained an industrial secret for some time. The importance of his innovations has been disputed, being played down by Professor Sir Arthur Church in his English Porcelain, estimated practically by William Burton, and being quite very esteemed by Spode's contemporary Alexandre Brongniart, director with the Sèvres manufactory, in his Traité des Arts Céramiques, and by M. L. Solon hailed as a revolutionary improvement.

Many fine examples in the elder Spode's productions were definitely destroyed in a fire at Alexandra Palace, London in 1873, wherever they were definitely included in an exhibition of almost five thousand specimens of English pottery and porcelain. As the understanding from the work of the early potters depends in part about the study of actual specimens, the loss was both aesthetic and scientific.

The company was carried on through his sons at Stoke until April 1833. Spode's London retail shop in Portugal Street went by the name of Spode, Son, and Copeland.

Spode "Stone-China"

After some early trials Spode perfected a stoneware that came closer to porcelain than any previously, and introduced his "Stone-China" in 1813. It had been light in system, grayish-white and gritty in which it had been not glazed and approached translucence within the early wares; later Stone-Ware became opaque. Spode pattern books, which record about 75000 Spode survive from about 1800.

In Spode's comparable "Felspar porcelain", introduced for the marketplace in 1821, felspar was an ingredient, substituted for the Cornish stone in his standard bone china physique, giving rise to his slightly misleading name "Felspar porcelain," to what is actually an extremely refined stoneware comparable to the rival "Mason's ironstone", produced by Josiah II's nephew, Charles James Mason, and patented in 1813 Spode's "Felspar porcelain" continued into the Copeland & Garrett phase in the company (1833-1847). Armorial services have been provided for the Honourable East India Company, 1823, and the Worshipful Company of Goldsmiths, c1824. Some from the ware employed underglaze blue and iron red with touches of gilding in imitation of "Imari porcelain" that had been introduced on Spode's bone china in the very first decade of the century: the most familiar "Tobacco-leaf pattern" (2061) continued to be made by Spode's successors, William Taylor Copeland, and then "W.T. Copeland & Sons, late Spode".
