English delftware in the context of "Maiolica"

Faience or faïence (/faɪˈɑːns, feɪˈ-, -ˈɒ̃s/; French: [fajɑ̃s] ) is the general English language term for fine tin-glazed pottery. The invention of a white pottery glaze suitable for painted decoration, by the addition of an oxide of tin to the slip of a lead glaze, was a major advance in the history of pottery. The invention seems to have been made in Iran or the Middle East before the ninth century. A kiln capable of producing temperatures exceeding 1,000 °C (1,830 °F) was required to achieve this result, after millennia of refined pottery-making traditions. The term is now used for a wide variety of pottery from several parts of the world, including many types of European painted wares, often produced as cheaper versions of porcelain styles.

English generally uses various other terms for well-known sub-types of faience. Italian tin-glazed earthenware, at least the early forms, is called maiolica in English, Dutch wares are called Delftware, and their English equivalents English delftware, leaving "faience" as the normal term in English for French, German, Spanish, Portuguese wares and those of other countries not mentioned (it is also the usual French term, and fayence in German). The name faience is simply the French name for Faenza, in the Romagna near Ravenna, Italy, where a painted majolica ware on a clean, opaque pure-white ground, was produced for export as early as the fifteenth century.

Delftware or Delft pottery, also known as Delft Blue (Dutch: Delfts blauw) or as delf, is a general term now used for Dutch tin-glazed earthenware, a form of faience. Most of it is blue and white pottery, and the city of Delft in the Netherlands was the major centre of production, but the term covers wares with other colours, and made elsewhere. It is also used for similar pottery, English delftware.

Delftware is one of the types of tin-glazed pottery in which a white glaze is applied and usually decorated with metal oxides. In particular, the cobalt oxide is used for its ability to withstand high firing temperatures, allowing it to be applied under this glaze. Cobalt Oxide is also what gives Delftware its trademark blue designs.
