Answer 1

Answer:

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, the result of 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.

Hispano-Moresque ware dish from Manises, 15th century, the earliest type of European faience.

Technically, lead-glazed earthenware, such as the French sixteenth-century Saint-Porchaire ware, does not properly qualify as faience, but the distinction is not usually maintained. Semi-vitreous stoneware may be glazed like faience. Egyptian faience is not really faience, or pottery, at all, but made of a vitreous frit, and so closer to glass.

In English 19th-century usage "faience" was often used to describe "any earthenware with relief modelling decorated with coloured glazes",[1] including much glazed architectural terracotta and Victorian majolica, adding a further complexity to the list of meanings of the word.

Answer 2

Chert is a sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2). It occurs as nodules, concretionary masses, and as layered deposits.

Chert breaks with a conchoidal fracture, often producing very sharp edges. Early people took advantage of how chert breaks and used it to fashion cutting tools and weapons. "Chert" and "flint" are names used for the same material. Both are varieties of chalcedony.

Faience is the term for tin-glazed earthenware made in France from the late sixteenth century until the end of the eighteenth century. ... Painted decoration composed of metallic oxides was then applied on top of the uniformly white glaze.

Terracotta, terra cotta, or terra-cotta (pronounced [ˌtɛrraˈkɔtta]; Italian: "baked earth", from the Latin terra cocta), a type of earthenware, is a clay-based unglazed or glazed ceramic, where the fired body is porous. ... The term is also used to refer to the natural brownish orange color of most terracotta.
