Silvery white metal. The third most abundant element in the earth’s crust (after oxygen and silicon), aluminium is found only in the form of its compounds, such as alumina or aluminium oxide. Its name is derived from alumen, the Latin name for alum, and in the 18th century the French word alumine was proposed for the oxide of the metal, then undiscovered. The name aluminium was adopted in the early 19th century and is used world-wide except in the USA, where the spelling is aluminum, and in Italy where alluminio is used. Following the discovery of processes for separating the metal from the oxide, at first experimentally in 1825, then commercially in 1854 and industrially in 1886–8, aluminium rapidly came to be valued as an adaptable material with both functional and decorative properties. Thus in addition to being used in engineering, transport, industrial design and household products, it was also widely adopted in architecture, sculpture and the decorative arts....

Founded in 1867, the Boston Society of Architects (BSA) is the oldest of the three Massachusetts chapters of the American Institute of Architects, established in 1857. Dominated by Edward Clark Cabot as its president for the first three decades, the Boston Society of Architects reflected the nature of the expanding practice in the city at that moment. Opened in the same year as the BSA was the nation’s first academic program in architecture at the Massachusetts Institute of Technology (MIT). In addition to the MIT courses, the BSA was soon joined by the first substantial professional journal in the country, The American Architect and Building News, which began publication in Boston in 1876. The Society served as both a professional and a social organization in its early years, allowing members to meet and learn from their fellow practitioners. A parallel organization, open to non-architects as well, was the Architecture Association created in ...

Popular art form, consisting of narrative series of images. The individual framed images are usually accompanied by text in white areas, and the conversations or thoughts of characters are usually in ‘balloons’. The language is associated with specific characters, although some strips are entirely pictorial. The strips are typically horizontal but occasionally vertical. The history of the comic strip is closely linked to the invention of printing. The earliest surviving ancestors of the modern strip, dating from the late 15th century, are sequential German woodcuts dealing with such themes as personal morality, crime, political intrigue, religious persecution, the lives of religious figures, and miraculous events. Similar efforts appeared during the 16th, 17th, and 18th centuries in the Netherlands, Italy, and Russia as well as in Germany.
More traditional European art forms are equally important to the development of the comic strip. Major print series by renowned artists, including Jacques Callot, ...
A representative work of art presented to and retained by the Royal Academy of Arts (see London, §VI) by each Academician on his or her election. Clause 3 of the Academy’s Instrument of Foundation, signed by George III in December 1768, specified that each newly elected Academician ‘shall not receive his letter of Admission, till he hath deposited in the Royal Academy, to remain there, a Picture, Bas-relief, or other specimen of his abilities, approved of by the then sitting Council of the Academy’. The practice of submitting a Diploma work, or Diploma piece, went back at least to the Accademia di S Luca, Rome, founded in 1593, although a less remote connection is to be found in the system organized by the Académie Royale de Peinture et de Sculpture in Paris, where every agréé had to submit a sample of work—a morceau de réception—prior to receiving formal admission into the Académie. (In France the admission of the ...
Place where works of art are displayed. In a commercial gallery, works of art are displayed for the purposes of sale (for information on non-commercial art galleries see Display of art and Museum, §I). Historically, artworks were commissioned by patrons directly from an artist and produced in his workshop. In the Netherlands, the economic boom following the conclusion of the Eighty Years’ War with Spain (1648) led to rising demand for art. Patrons began buying from dealers, some of whom produced illustrated catalogues. Antwerp became the centre of the art world. Galleries for the display and viewing of art appeared in paintings by Teniers family, §2 and Bruegel family, §3, although these were private not commercial spaces, or imaginary constructions.
The Paris Salon, which had been organized by the Académie Royale de Peinture et Sculpture since 1667, was opened to the public for the first time in ...
Medium utilizing oxidized metal particles carried on a flexible substrate, in order to record an electronic signal, most commonly in the form of audiotape or videotape. Magnetic tape is also used in computers for the storage of data, but this usage is unlikely to be encountered in an art conservation context.
Magnetic recording tape generally is made up of a plastic film base (most tapes, including all videotapes, have a base of polyester terephthalate (PET)), coated on one side with a binder system containing oxidized metal particles. Often, recording tape will also have what is known as a backcoating on the reverse side, which reduces friction, dissipates the buildup of static electricity, and allows for the tape to be more evenly wound. Some early audiotapes had paper backing, while others may also have a backing of acetate plastic, which is subject to the same deterioration factors as acetate photographic film, including so-called ‘vinegar syndrome’. The binder layer, the most critical component of the recording tape, usually consists of metal particles suspended in a binder of polyester and polyurethane, although it can contain numerous other chemicals. Different manufacturers have used different binder formulations, and changed them frequently over time. For this reason, some tapes may be more subject to deterioration than others of similar age and format. In the 1980s, manufacturers began to produce tapes with no binder polymer, but instead a very thin layer of metal alloy evaporated onto the tape base, known as ‘metal evaporated’ or ME tapes. The binder system may also contain lubricants designed to minimize friction as the tape passes through a recording or playback device....
Medium on which a series of photographic images are recorded on a flexible plastic base in order to produce the illusion of movement when reproduced by projection through a lens or other means. Although ‘film’ has been used by the general public as a catch-all term for any moving image medium, it actually refers specifically to photochemical reproduction.
Three different types of film base have been used in motion picture production. The first, cellulose nitrate, was used from the time it was introduced by Eastman Kodak in 1889, through the early 1950s. Cellulose nitrate was durable, withstood repeated projection, and provided a high-quality image. It was also extremely flammable, requiring careful handling in shipping and storage, and the construction of special fireproof projection booths in theatres. It is always identified by the words ‘Nitrate film’ along one edge. Cellulose acetate film was first made available commercially in 1909, but was inferior in strength to nitrate film, and was not widely adopted for theatrical use. It was, however, used exclusively in smaller-gauge film for home and amateur use by the 1920s. In ...
Italian family of stonecarvers active in America. At the turn of the century, when the craze for classical architecture was at its height, statues in marble were produced in great quantity for buildings and public spaces. Since the early 19th century, it had been common to separate the design process of creating a model in clay or plaster, and the task of actually carving the marble block. To take advantage of the skills of Italian craftsmen, in the early 19th century many American sculptors established studios in Rome or Florence. By the turn of the century, however, many Italian craftsmen immigrated to the United States in order to work more easily with American sculptors and architects, and to take advantage of the American building boom. Among this group were the Piccirilli brothers, who established the most successful statuary and stone carving business that has ever existed in America. The patriarch of the Piccirilli clan, Giuseppe (...
American family of Philadelphia printmakers, printers, painters, and educators. John Sartain and his children, Emily and William, played an important role in the art world of Philadelphia for over a century. Their influence on American art lies primarily in the impact of their work example and leadership on others, and somewhat less from the value placed on their own artistic output. The patriarch, John Sartain (b London, 24 Oct 1808; d Philadelphia, PA, 25 Oct 1897), arrived in Philadelphia at the age of 22. By 1850 he was the city’s premier engraver of illustrations for a wide range of publications. His brilliant mezzotint engravings, often reproducing the work of others, brought graphic art into the homes of all classes. Reproductive engravings, either framed or in books, were widely popular before the advent of photography. Many writers promulgated the display of such prints as a means to refine and enlighten society. Sartain’s most successful endeavours in this field were his large and elaborate framing prints, commissioned by painters, collectors, and publishers to disseminate important works. The finest of these is ...

Stonecarving throughout American history has been utilized for various purposes: utilitarian work such as paving, roofing and hitching posts; and ornamental work, such as architectural elements, gravestones and monuments, and sculpture. America’s first professional stonecarvers were mainly trained, skilled artisans from England and Scotland. These men were often called “statuaries” because they were capable of producing highly ornamental carving and sculpture, similar to the work of trained academic sculptors. There was little call for such highly decorative work in the colonies, but as urban centers gradually formed, stone masons found plenty of work in newly emerging cities such as Boston, Philadelphia and New York.
In rural areas many of America’s early stonecarvers were native-born and self-taught. Their skills were most often put to use carving gravestones, which were needed in every community. Both professional and native-born stonecarvers produced beautiful, often idiosyncratic carved work. They worked in the “direct” method of carving, that is carving directly into the stone without creating a preliminary model. Botanist John Bartram designed his own stone house in Philadelphia around ...
