Tin-glazing
Tin-glazing is the process of giving tin-glazed pottery items a ceramic glaze that is white, glossy and opaque, which is normally applied to red or buff earthenware. Tin-glaze is plain lead glaze with a small amount of tin oxide added.Caiger-Smith, Alan, ''Tin-Glaze Pottery in Europe and the Islamic World: The Tradition of 1000 Years in Maiolica, Faience and Delftware'', London, Faber and Faber, 1973 The opacity and whiteness of tin glaze encourage its frequent decoration. Historically this has mostly been done before the single firing, when the colours blend into the glaze, but since the 17th century also using overglaze enamels, with a light second firing, allowing a wider range of colours. Majolica, maiolica, delftware and faience are among the terms used for common types of tin-glazed pottery. An alternative is lead-glazing, where the basic glaze is transparent; some types of pottery use both. However, when pieces are glazed only with lead, the glaze becomes fluid during f ...

Majolica
In different periods of time and in different countries, the term ''majolica'' has been used for two distinct types of pottery. Firstly, from the mid-15th century onwards, was ''maiolica'', a type of pottery reaching Italy from Spain, Majorca and beyond. This was made by a tin-glaze process (dip, dry, paint, fire), resulting in an opaque white glazed surface decorated with brush-painting in metal oxide enamel colour(s). During the 17th century, the English added the letter '' j'' to their alphabet. ''Maiolica'' was commonly anglicized to ''majolica'' thereafter. The second style of pottery known as ''majolica'' is the mid- to late-19th century Victorian style made by a simpler process (painting and then firing) whereby coloured lead silicate glazes were applied directly to an unfired clay mould, typically relief-moulded, resulting in brightly coloured, hard-wearing, inexpensive wares that were both useful and decorative, typically in naturalistic style. This type of majolica wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tin-glazed Pottery
Tin-glazed pottery is earthenware covered in lead glaze with added tin oxide which is white, shiny and opaque (see tin-glazing for the chemistry); usually this provides a background for brightly painted decoration. It has been important in Islamic and European pottery, but very little used in East Asia. The pottery body is usually made of red or buff-colored earthenware and the white glaze imitated Chinese porcelain. The decoration on tin-glazed pottery is usually applied to the unfired glaze surface by brush with metallic oxides, commonly cobalt oxide, copper oxide, iron oxide, manganese dioxide and antimony oxide. The makers of Italian tin-glazed pottery from the late Renaissance blended oxides to produce detailed and realistic polychrome paintings. The earliest tin-glazed pottery appears to have been made in Iraq in the 9th century, the oldest fragments having been excavated during the First World War from the palace of Samarra about fifty miles north of Baghdad.Caiger-Sm ...

Ceramic Glaze
Ceramic glaze is an impervious layer or coating of a vitreous substance which has been fused to a pottery body through firing. Glaze can serve to color, decorate or waterproof an item. Glazing renders earthenware vessels suitable for holding liquids, sealing the inherent porosity of unglazed biscuit earthenware. It also gives a tougher surface. Glaze is also used on stoneware and porcelain. In addition to their functionality, glazes can form a variety of surface finishes, including degrees of glossy or matte finish and color. Glazes may also enhance the underlying design or texture either unmodified or inscribed, carved or painted. Most pottery produced in recent centuries has been glazed, other than pieces in unglazed biscuit porcelain, terracotta, or some other types. Tiles are almost always glazed on the surface face, and modern architectural terracotta is very often glazed. Glazed brick is also common. Domestic sanitary ware is invariably glazed, as are many ceramics u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luca Della Robbia
Luca della Robbia (, also , ; 1399/1400–1482) was an Italian Renaissance sculptor from Florence. Della Robbia is noted for his colorful, Tin-glazed pottery, tin-glazed terracotta statuary, a technique which he invented and passed on to his nephew Andrea della Robbia and great-nephews Giovanni della Robbia and Girolamo della Robbia. Though a leading sculptor in stone, he worked primarily in terracotta after developing his technique in the early 1440s. His large workshop produced both cheaper works cast from molds in multiple versions, and more expensive one-off individually modeled pieces. The vibrant, polychrome glazes made his creations both more durable and expressive. His work is noted for its charm rather than the drama of the work of some of his contemporaries. Two of his famous works are ''The Nativity'' () and ''Madonna and Child'' (). In stone his most famous work is also his first major commission, the choir gallery, ''Cantoria'' in the Florence Cathedral (1431–143 ...

Stoneware
Stoneware is a rather broad term for pottery or other ceramics fired at a relatively high temperature. A modern technical definition is a Vitrification#Ceramics, vitreous or semi-vitreous ceramic made primarily from stoneware clay or non-refractory fire clay. Whether vitrified or not, it is nonporous (does not soak up liquids);Arthur Dodd & David Murfin. ''Dictionary of Ceramics''; 3rd edition. The Institute of Minerals, 1994. it may or may not be glaze (ceramics), glazed. Historically, around the world, it has been developed after earthenware and before porcelain, and has often been used for high-quality as well as utilitarian wares. As a rough guide, modern earthenwares are normally fired in a kiln at temperatures in the range of about 1,000 °Celsius, C (1,830 Fahrenheit, °F) to ; stonewares at between about to ; and porcelains at between about to . Historically, reaching high temperatures was a long-lasting challenge, and temperatures somewhat below these were used for a lo ...

Samarra
Samarra ( ar, سَامَرَّاء, ') is a city in Iraq. It stands on the east bank of the Tigris in the Saladin Governorate, north of Baghdad. The city of Samarra was founded by Abbasid Caliph Al-Mutasim for his Turkish professional army of around 3,000 soldiers which grew to tens of thousands later. In 2003 the city had an estimated population of 348,700. During the Iraqi Civil War, Samarra was in the "Sunni Triangle" of resistance. In medieval times, Samarra was the capital of the Abbasid Caliphate and is the only remaining Islamic capital that retains its original plan, architecture and artistic relics. In 2007, UNESCO named Samarra one of its World Heritage Sites. History Prehistoric Samarra The remains of prehistoric Samarra were first excavated between 1911 and 1914 by the German archaeologist Ernst Herzfeld. Samarra became the type site for the Samarra culture. Since 1946, the notebooks, letters, unpublished excavation reports and photographs have been in th ...
