Sevres porcelain

Whereas most chemists focused their attention on speculation about atoms and the question of atomic weights, the constant multiplicity in compounds occupied an increasingly central role. The new concept of substitution, i.e., the replacement of one element by another in a compound, started to make a major impact on chemistry in the 1840s. It was probably Dumas, who in the 1830s at the request of his father-in-law (who was the director of the famous Royal Sevres porcelain factory) resolved an event that upset a royal dinner party at the Tuil-...

The salts have been used for centuries to produce brilliant and permanent blue colors in porcelain, glass, pottery, tiles, and enamels. It is the principal ingredient in Sevre s and Thenard s blue. A solution of the chloride is used as a sympathetic ink. Cobalt carefully used in the form of the chloride, sulfate, acetate, or nitrate has been found effective in correcting a certain mineral deficiency disease in animals. 

Some very interesting and important experiments have been made by Beog-mart and Malaguti, with reference to the nature of porcelain, and which also furnish valuable hints connected with its manufacture. Masses of porcelain day, composed of different suitable materials, and affording the same per centnge composition as the porcelain mixture adopted during the last sixty years at Sevres, 68 silica, 34 5 alumina, 4-5 lime, and 3 potassa—were submitted to the different processes. of manufacture with the following results —... 

Mus6e National de C6ramique at Sevres, France. The collection includes examples of early European porcelains including a Medici porcelain bottle made in 1581 the first success in European efforts to produce ware equivalent to Persian and Chinese porcelain. It also contains examples of French soft-paste porcelain as well as earlier ceramics. www.ceramique.conL... 

Regnault s later research was almost exclusively in physics the specific heats of solids and gases, densities and compressibilities of gases, properties of steam, etc., and his results in this field are very accurate. He became professor of physics in the College de France and director of the porcelain factory at Sevres (1854). In the war of 1870 his son was killed in battle and his laboratory at Sevres was deliberately wrecked and his papers destroyed by the Prussian army. His chemical publications are on Dutch liquid, etc., the aldehydene theory (see p. 355), the identity of equisitic and maleic acids, the action of steam on heated metals and sulphides, sulphonaphthalic acid, and the action of sulphur trioxide on organic substances,methyl sulphate, mineral combustibles, alkaloids, diallage, potassium and lithium micas, the action of chlorine on Dutch liquid, sulphuryl chloride and sulphamide, chlorides of carbon, determination of carbon in cast iron and steel, action of chlorine on ethers, sulphuryl chloride, report on the Marsh test, respiration (with... 

Macquer worked on the production of true porcelain at Sevres, the first successful results with kaolin from St. Yrieix being obtained in 1765, and in 1769 the production of the first true French porcelain was begun. ... 

Soft-paste or Fritted Porcelain. A type of porcelain made from a soft body containing a glassy frit and fired at a comparatively low temperature (1100°C). The most famous soft-paste ware was that produced in the 18th century at the Sevres factory in France, and at Chelsea, Derby, Bow, Worcester and Longton Hall in England. The COMBINED nomenclature (q.v.) States that soft porcelain contains less alumina but more silica and fluxes than hard porcelain. See porcelain. 

The number of academic entries in the Google-Academic search tool is around 1200 (as of March 2014) (Figure 37.1), and the academic publications is about 98% of total publications. We can consider three main steps in the development of ceramic pigments for glazed ceramics (i) before the discovery of European porcelain (1710), after this discovery up to 1900 with the introduction of the green of Sevres as the main relevant novelty in 1802, (ii) the twentieth century with the discovery of the zircon stain family, and (iii) the twenty-first century with the development of submicrometer size pigments for inkjet applications.
