Barbotine is the French for ceramic slip, or a mixture of clay and water used for moulding or decorating pottery. [1] In English the term is used for three different techniques of decorating pottery, though in all cases mainly for historical works. For clarity, these types are numbered here as A-C (which are not standard terms).
In the first, common from the Ancient World onwards, the barbotine is piped onto the object rather as cakes are decorated with icing, using a quill, horn, or other kind of nozzle. The slip would normally be in a contrasting colour to the rest of the vessel, and forms a pattern, or inscription, that is slightly raised above the main surface. This is normally called slip-trailing in English today, and for English pottery (such as the works of Thomas Toft, d. 1698), but "barbotine" remains common in archaeology.
The first barbotine technique in pottery styling was in use in the ancient world. The Egyptians were known to have used barbotine design. [2] As another example, Middle Minoan pottery from Knossos on the island of Crete in present-day Greece includes a barbotine pottery style, [3] and it is common in Ancient Roman pottery, where the colour may often be the same as the rest of the vessel.
The second technique is a term for slipcasting, "couler en barbotine" in French. "Barbotine pottery" is sometimes used for Ancient Roman as well as 19th-century French and American pottery with added slipcast decoration. Slip or barbotine is cast in moulds to form three-dimensional decorative sections which when dried out are added to the main vessel. [4] Typically, these might be flowers, fruit, or small animals. Again, there is an alternative English term, Sprigging (pottery), which is normally used for English pottery, for example in Wedgwood's Jasperware, where the sprigs are in contrasting colours.
The third sense of the term describes a technique developed by Ernest Chaplet, the secret of which was later sold by him to Haviland & Co. This was a method of painting art pottery in brightly-coloured slips, in French also called peinture à la barbotine or in gouache vitrifiable. In this type there may be some impasto, but the decoration is essentially close to the surface. The term "Barbotine ware" also describes the American art pottery that emulated the Haviland pottery, which made a great impression at the 1876 Philadelphia Centennial Exposition. [5] In America this led to the technique sometimes being called "Limoges ware", Haviland being a large maker of Limoges porcelain. In fact all their barbotine wares were made at their factory in Auteuil, near Paris. [6]
The technique and term were less frequently used in England, although the technique was used, typically for floral paintings, by potteries including the Watcombe Pottery and the Bretby Art Pottery. [7]
This sense of the term entered English via French potteries such as Sèvres and the Haviland Company of Limoges, who used it to describe their pottery in the second half of the 19th century. The precise technique varied between ceramicists. Some applied the coloured slips to unfired greenware, others to fired pots. On darker clay bodies an overall light coat of slip was often applied first. [8]
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. 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". End applications include tableware, decorative ware, sanitaryware, and in technology and industry such as electrical insulators and laboratory ware. 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.
Faience or faïence 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, 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.
Terra sigillata is a term with at least three distinct meanings: as a description of medieval medicinal earth; in archaeology, as a general term for some of the fine red Ancient Roman pottery with glossy surface slips made in specific areas of the Roman Empire; and more recently, as a description of a contemporary studio pottery technique supposedly inspired by ancient pottery. Usually roughly translated as 'sealed earth', the meaning of 'terra sigillata' is 'clay bearing little images', not 'clay with a sealed (impervious) surface'. The archaeological term is applied, however, to plain-surfaced pots as well as those decorated with figures in relief.
Slipware is pottery identified by its primary decorating process where slip is placed onto the leather-hard (semi-hardened) clay body surface before firing by dipping, painting or splashing. Slip is an aqueous suspension of a clay body, which is a mixture of clays and other minerals such as quartz, feldspar and mica. The slip placed onto a wet or leather-hard clay body surface by a variety of techniques including dipping, painting, piping or splashing. Slipware is the pottery on which slip has been applied either for glazing or decoration. Slip is liquified clay or clay slurry, with no fixed ratio of water and clay, which is used either for joining pottery pieces together by slip casting with mould, glazing or decorating the pottery by painting or dipping the pottery with slip.
Slip casting, or slipcasting, is a ceramic forming technique, and is widely used for shapes that can not easily be formed by other techniques. The technique involves a clay body slip, usually prepared in a blunger, being poured into plaster moulds and allowed to form a layer, the cast, on the internal walls of the mould.
Biscuit porcelain, bisque porcelain or bisque is unglazed, white porcelain treated as a final product, with a matte appearance and texture to the touch. It has been widely used in European pottery, mainly for sculptural and decorative objects that are not tableware and so do not need a glaze for protection.
Minoan pottery has been used as a tool for dating the mute Minoan civilization. Its restless sequence of quirky maturing artistic styles reveals something of Minoan patrons' pleasure in novelty while they assist archaeologists in assigning relative dates to the strata of their sites. Pots that contained oils and ointments, exported from 18th century BC Crete, have been found at sites through the Aegean islands and mainland Greece, on Cyprus, along coastal Syria and in Egypt, showing the wide trading contacts of the Minoans.
Mintons was a major company in Staffordshire pottery, "Europe's leading ceramic factory during the Victorian era", an independent business from 1793 to 1968. It was a leader in ceramic design, working in a number of different ceramic bodies, decorative techniques, and "a glorious pot-pourri of styles - Rococo shapes with Oriental motifs, Classical shapes with Medieval designs and Art Nouveau borders were among the many wonderful concoctions". As well as pottery vessels and sculptures, the firm was a leading manufacturer of tiles and other architectural ceramics, producing work for both the Houses of Parliament and United States Capitol.
Sprigging or sprigged decoration is a technique for decorating pottery with low relief shapes made separately from the main body and applied to it before firing. Usually thin press moulded shapes are applied to greenware or bisque. The resulting pottery is termed sprigged ware, and the added piece is a "sprig". The technique may also be described by terms such as "applied relief decoration", especially in non-European pottery.
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.
Pâte-sur-pâte is a French term meaning "paste on paste". It is a method of porcelain decoration in which a relief design is created on an unfired, unglazed body, usually with a coloured body, by applying successive layers of (usually) white porcelain slip with a brush. Once the main shape is built up, it is carved away to give fine detail, before the piece is fired. The work is very painstaking and may take weeks of adding extra layers and allowing them to harden before the next is applied.
Mycenaean pottery is the pottery tradition associated with the Mycenaean period in Ancient Greece. It encompassed a variety of styles and forms including the stirrup jar. The term "Mycenaean" comes from the site Mycenae, and was first applied by Heinrich Schliemann.
Thomas Toft was an English potter working in the Staffordshire Potteries during the 17th century. He and his family are known for large earthenware plates heavily decorated by slip-trailing, often in several colours. Work in this style, even by other makers, is known as Toft ware.
Kamares ware is a distinctive type of Minoan pottery produced in Crete during the Minoan period, dating to MM IA. By the LM IA period, or the end of the First Palace Period, these wares decline in distribution and "vitality". They have traditionally been interpreted as a prestige artifact, possibly used as an elite table-ware.
Minoan art is the art produced by the Bronze Age Aegean Minoan civilization from about 3000 to 1100 BC, though the most extensive and finest survivals come from approximately 2300 to 1400 BC. It forms part of the wider grouping of Aegean art, and in later periods came for a time to have a dominant influence over Cycladic art. Since wood and textiles have decomposed, the best-preserved surviving examples of Minoan art are its pottery, palace architecture, small sculptures in various materials, jewellery, metal vessels, and intricately-carved seals.
Art pottery is a term for pottery with artistic aspirations, made in relatively small quantities, mostly between about 1870 and 1930. Typically, sets of the usual tableware items are excluded from the term; instead the objects produced are mostly decorative vessels such as vases, jugs, bowls and the like which are sold singly. The term originated in the later 19th century, and is usually used only for pottery produced from that period onwards. It tends to be used for ceramics produced in factory conditions, but in relatively small quantities, using skilled workers, with at the least close supervision by a designer or some sort of artistic director. Studio pottery is a step up, supposed to be produced in even smaller quantities, with the hands-on participation of an artist-potter, who often performs all or most of the production stages. But the use of both terms can be elastic. Ceramic art is often a much wider term, covering all pottery that comes within the scope of art history, but "ceramic artist" is often used for hands-on artist potters in studio pottery.
Pottery was produced in enormous quantities in ancient Rome, mostly for utilitarian purposes. It is found all over the former Roman Empire and beyond. Monte Testaccio is a huge waste mound in Rome made almost entirely of broken amphorae used for transporting and storing liquids and other products – in this case probably mostly Spanish olive oil, which was landed nearby, and was the main fuel for lighting, as well as its use in the kitchen and washing in the baths.
Cizhou ware or Tz'u-chou ware is a term for a wide range of Chinese ceramics from between the late Tang dynasty and the early Ming dynasty, but especially associated with the Northern Song to Yuan period in the 11–14th century. It has been increasingly realized that a very large number of sites in northern China produced these wares, and their decoration is very variable, but most characteristically uses black and white, in a variety of techniques. For this reason Cizhou-type is often preferred as a general term. All are stoneware in Western terms, and "high-fired" or porcelain in Chinese terms. They were less high-status than other types such as celadons and Jun ware, and are regarded as "popular", though many are finely and carefully decorated.
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.
