Agateware is pottery decorated with a combination of contrasting colored clays.
The name agateware is derived from the agate stone, which when sliced shows multicolored layers. This pottery technique allows for both precise and thought out patterns, and free random effects.
In order to avoid cracking and breaking which come along with mixing a variety of different kinds of clay, potters generally use one white or very light clay as a base. They then add colors in the form of stains or oxides. Colorant is added to the clay when it is in powder form in order to avoid blistering. 1–10% of colorant is generally applied, however it is up to the individual taste of the potter. The drying process is the most crucial part of this technique.
In Japan it is called nerikomi .
Pottery is the process and the products of forming vessels and other objects with clay and other raw materials, which are fired at high temperatures to give them a hard and durable form. Major types include earthenware, stoneware and porcelain. The place where such wares are made by a potter is also called a pottery. The definition of pottery, used by the ASTM International, is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products". In art history and archaeology, especially of ancient and prehistoric periods, "pottery" often means vessels only, and sculpted figurines of the same material are called "terracottas".
Raku ware is a type of Japanese pottery traditionally used in Japanese tea ceremonies, most often in the form of chawan tea bowls. It is traditionally characterised by being hand-shaped rather than thrown, fairly porous vessels, which result from low firing temperatures, lead glazes and the removal of pieces from the kiln while still glowing hot. In the traditional Japanese process, the fired raku piece is removed from the hot kiln and is allowed to cool in the open air.
Pottery and porcelain, is one of the oldest Japanese crafts and art forms, dating back to the Neolithic period. Kilns have produced earthenware, pottery, stoneware, glazed pottery, glazed stoneware, porcelain, and blue-and-white ware. Japan has an exceptionally long and successful history of ceramic production. Earthenwares were made as early as the Jōmon period, giving Japan one of the oldest ceramic traditions in the world. Japan is further distinguished by the unusual esteem that ceramics holds within its artistic tradition, owing to the enduring popularity of the tea ceremony.
In pottery, a potter's wheel is a machine used in the shaping of clay into round ceramic ware. The wheel may also be used during the process of trimming excess clay from leather-hard dried ware that is stiff but malleable, and for applying incised decoration or rings of colour. Use of the potter's wheel became widespread throughout the Old World but was unknown in the Pre-Columbian New World, where pottery was handmade by methods that included coiling and beating.
Salt-glaze or salt glaze pottery is pottery, usually stoneware, with a glaze of glossy, translucent and slightly orange-peel-like texture which was formed by throwing common salt into the kiln during the higher temperature part of the firing process. Sodium from the salt reacts with silica in the clay body to form a glassy coating of sodium silicate. The glaze may be colourless or may be coloured various shades of brown, blue, or purple.
Bizen ware is a type of Japanese pottery traditionally from Bizen province, presently a part of Okayama prefecture.
Shino ware is Japanese pottery, usually stoneware, originally from Mino Province, in present-day Gifu Prefecture, Japan. It emerged in the 16th century, but the use of shino glaze is now widespread, both in Japan and abroad. It is identified by thick white glazes, red scorch marks, and a texture of small holes. Some experts believe it should not be treated as distinct from Oribe ware but described as "white Oribe", with the pottery usually called just Oribe described as "green Oribe" instead.
Maria Montoya Martinez was a Native American artist who created internationally known pottery. Martinez, her husband Julian, and other family members, including her son Popovi Da, examined traditional Pueblo pottery styles and techniques to create pieces which reflect the Pueblo people's legacy of fine artwork and crafts. The works of Maria Martinez, and especially her black ware pottery, survive in many museums, including the Smithsonian, the Metropolitan Museum of Art, the Denver Art Museum, and more. The Penn Museum in Philadelphia holds eight vessels – three plates and five jars – signed either "Marie" or "Marie & Julian".
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. 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.
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.
A slip is a clay slurry used to produce pottery and other ceramic wares. Liquified clay, in which there is no fixed ratio of water and clay, is called slip or clay slurry which is used either for joining leather-hard (semi-hardened) clay body together by slipcasting with mould, glazing or decorating the pottery by painting or dipping the pottery with slip. Pottery on which slip has been applied either for glazing or decoration is called the slipware.
This is a list of pottery and ceramic terms.
Ceramic colorants are added to a glaze or a clay to create color. Carbonates and oxides of certain metals, characterize most colorants including the commonly used cobalt carbonate, cobalt oxide, chrome oxide, red iron oxide, and copper carbonate. These colorants can create a multitude of colors depending on other materials they interact with and to which temperature and in which atmosphere they are fired.
Ceramics in Mexico date back thousands of years before the Pre-Columbian period, when ceramic arts and pottery crafts developed with the first advanced civilizations and cultures of Mesoamerica. With one exception, pre-Hispanic wares were not glazed, but rather burnished and painted with colored fine clay slips. The potter's wheel was unknown as well; pieces were shaped by molding, coiling and other methods,
Mississippian culture pottery is the ceramic tradition of the Mississippian culture found as artifacts in archaeological sites in the American Midwest and Southeast. It is often characterized by the adoption and use of riverine shell-tempering agents in the clay paste. Shell tempering is one of the hallmarks of Mississippian cultural practices. Analysis of local differences in materials, techniques, forms, and designs is a primary means for archaeologists to learn about the lifeways, religious practices, trade, and interaction among Mississippian peoples. The value of this pottery on the illegal antiquities market has led to extensive looting of sites.
Mata Ortiz pottery is a recreation of the Mogollon pottery found in and around the archeological site of Casas Grandes (Paquimé) in the Mexican state of Chihuahua. Named after the modern town of Mata Ortiz, which is near the archeological site, the style was propagated by Juan Quezada Celado. Quezada learned on his own to recreate this ancient pottery and then went on to update it. By the mid 1970s, Quezada was selling his pottery and teaching family and friends to make it and the pottery was able to penetrate the U.S. markets thanks to efforts by Spencer MacCallum and later Walt Parks along with Mexican traders. By the 1990s, the pottery was being shown in museums and other cultural institutions and sold in fine galleries. The success of the pottery, which is sold for its aesthetic rather than its utilitarian value, has brought the town of Mata Ortiz out of poverty, with most of its population earning income from the industry, directly or indirectly.
Horezu ceramics is a unique type of Romanian pottery that is traditionally produced by hand around the town of Horezu in northern Oltenia, close to the famous Horezu Monastery. It reflects many generations of knowledge and skills development of pottery, which is why the craftsmanship of Horezu pottery was inscribed on UNESCO Intangible Cultural Heritage Lists in December 2012.
Ceramic art is art made from ceramic materials, including clay. It may take forms including artistic pottery, including tableware, tiles, figurines and other sculpture. As one of the plastic arts, ceramic art is one of the visual arts. While some ceramics are considered fine art, such as pottery or sculpture, most are considered to be decorative, industrial or applied art objects. Ceramics may also be considered artefacts in archaeology. Ceramic art can be made by one person or by a group of people. In a pottery or ceramic factory, a group of people design, manufacture and decorate the art ware. Products from a pottery are sometimes referred to as "art pottery". In a one-person pottery studio, ceramists or potters produce studio pottery.
The conservation and restoration of ancient Greek pottery is a sub-section of the broader topic of conservation and restoration of ceramic objects. Ancient Greek pottery is one of the most commonly found types of artifacts from the ancient Greek world. The information learned from vase paintings forms the foundation of modern knowledge of ancient Greek art and culture. Most ancient Greek pottery is terracotta, a type of earthenware ceramic, dating from the 11th century BCE through the 1st century CE. The objects are usually excavated from archaeological sites in broken pieces, or shards, and then reassembled. Some have been discovered intact in tombs. Professional conservator-restorers, often in collaboration with curators and conservation scientists, undertake the conservation-restoration of ancient Greek pottery.
Ancient Egyptian pottery includes all objects of fired clay from ancient Egypt. First and foremost, ceramics served as household wares for the storage, preparation, transport, and consumption of food, drink, and raw materials. Such items include beer and wine mugs and water jugs, but also bread moulds, fire pits, lamps, and stands for holding round vessels, which were all commonly used in the Egyptian household. Other types of pottery served ritual purposes. Ceramics are often found as grave goods.
