Glass Art
Glass art refers to individual works of art that are substantially or wholly made of glass. It ranges in size from monumental works and installation pieces to wall hangings and windows, to works of art made in studios and factories, including glass jewelry and tableware. As a decorative and functional medium, glass was extensively developed in Egypt and Assyria. Glassblowing was perhaps invented in the 1st century BC, and featured heavily in Roman glass, which was highly developed with forms such as the cage cup for a luxury market. Islamic glass was the most sophisticated of the early Middle Ages. Then the builders of the great Norman and Gothic cathedrals of Europe took the art of glass to new heights with the use of stained glass windows as a major architectural and decorative element. Glass from Murano, in the Venetian Lagoon, (also known as Venetian glass) is the result of hundreds of years of refinement and invention. Murano is still held as the birthplace of modern glass ...

Molding (process)
Molding (American English) or moulding (British and Commonwealth English; see spelling differences) is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or matrix. This itself may have been made using a pattern or model of the final object. A mold or mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material. The liquid hardens or sets inside the mold, adopting its shape. A mold is a counterpart to a cast. The very common bi-valve molding process uses two molds, one for each half of the object. Articulated molds have multiple pieces that come together to form the complete mold, and then disassemble to release the finished casting; they are expensive, but necessary when the casting shape has complex overhangs. Piece-molding uses a number of different molds, each creating a section of a complicated object. This is generally only used for larger a ...

Vitreography
Vitreography is a fine art printmaking technique that uses a float glass matrix instead of the traditional matrices of metal, wood or stone. A print created using the technique is called a vitreograph. Unlike a monotype, in which ink is painted onto a smooth glass plate and transferred to paper to produce a unique work, the vitreograph technique involves fixing the imagery in, or on, the glass plate. This allows the production of an edition of prints. Advantages/disadvantages of vitreography In addition to being relatively inexpensive, glass is chemically inert. It does not oxidize, nor does it change or interact with the composition of printing inks, especially yellows and whites, which can turn green or gray in contact with metal plates. According to Claire Van Vliet of Janus Press, intaglio vitreographs also have an advantage over metal in that the glass plate wipes cleanly in non-image areas, allowing bright white to coincide with “black that is velvety as a mezzotintâ ...

Vitreography (art Form)
As an art form, vitreography is a style of contained 3-dimensional scenes displayed in a shadow box frame. Process and effect Elements of the scene are isolated and drawn/painted on separate, suspended glass panes. The elements merge in the shadow box frame, utilizing the glass' transparency, to give a layered dimensionality to the scene and its components. Depending on the angle of perception, background, ground, and foreground will all interact differently. Through this method the artist is given a new axis of expression with which to experiment and engage an audience. In this way, vitreography may be seen as the fine art rendition of the Ken Burns effect, giving new dimension and life to still images. Origins Both the particular art form and the application of the term "vitreography" were pioneered by the French-American artist Jean-Pierre Weill, Weill having trademarked A trademark (also written trade mark or trade-mark) is a type of intellectual property consi ...

Studio Glass
Studio glass is the modern use of glass as an artistic medium to produce sculptures or three-dimensional artworks. The glass objects created are intended to make a sculptural or decorative statement. Though usage varies, the term is properly restricted to glass made as art in small workshops, typically with the personal involvement of the artist who designed the piece. This is in contrast to art glass, made by craftsmen in factories, and glass art, covering the whole range of glass with artistic interest made throughout history. Both art glass and studio glass originate in the 19th century, and the terms compare with studio pottery and art pottery, but in glass the term "studio glass" is mostly used for work made in the period beginning in the 1960s with a major revival in interest in artistic glassmaking. Pieces are often unique, or made in a small limited edition. Their prices may range from a few hundred to hundreds of thousands of dollars (US). For the largest installati ...

Punty
Glassblowing is a glassforming technique that involves inflating molten glass into a bubble (or parison) with the aid of a blowpipe (or blow tube). A person who blows glass is called a ''glassblower'', ''glassmith'', or ''gaffer''. A ''lampworker'' (often also called a glassblower or glassworker) manipulates glass with the use of a torch on a smaller scale, such as in producing precision laboratory glassware out of borosilicate glass. Technology Principles As a novel glass forming technique created in the middle of the 1st century BC, glassblowing exploited a working property of glass that was previously unknown to glassworkers; inflation, which is the expansion of a molten blob of glass by introducing a small amount of air into it. That is based on the liquid structure of glass where the atoms are held together by strong chemical bonds in a disordered and random network,Frank, S 1982. Glass and Archaeology.

Prunt
A prunt is a small blob of glass fused to another piece of glass. Prunts are applied primarily as decoration, but also help provide a firm grip in the absence of a handle. Prunts may be impressed into decorative shapes, such as raspberries, blackberries, or lion's heads. Prunts are a common stylistic element in German glassware, such as the rummer and Berkemeyer A Berkemeyer is a drinking glass with a wide, flared bowl, dating from 15th-century Germany and the Netherlands, and still made today.

Murrine
Murrine (singular: murrina) are colored patterns or images made in a glass cane that are revealed when the cane is cut into thin cross-sections. Murrine can be made in infinite designs from simple circular or square patterns to complex detailed designs to even portraits of people. One familiar style is the flower or star shape which, when used together in large numbers from a number of different canes, is called millefiori. Murrine production first appeared in the Middle East more than 4,000 years ago and was revived by Venetian glassmakers on Murano in the early 16th century.Carl I. Gable, ''Murano Magic: Complete Guide to Venetian Glass, its History and Artists'' (Schiffer, 2004), p. 37. . Once murrine have been made, they can be incorporated into a glass vessel or sculpture in several ways. A number of murrine may be scattered, more or less randomly, on a marver (steel table) and then picked up on the surface of a partially-blown glass bubble. Further blowing, heating, and ...

Millefiori
Millefiori () is a glasswork technique which produces distinctive decorative patterns on glassware. The term millefiori is a combination of the Italian words "mille" (thousand) and "fiori" (flowers). Apsley Pellatt in his book ''Curiosities of Glass Making'' was the first to use the term "millefiori", which appeared in the ''Oxford English Dictionary'' in 1849; prior to that, the beads were called mosaic beads. While the use of this technique long precedes the term "millefiori", it is now most frequently associated with Venetian glassware. Since the late 1980s, the millefiori technique has been applied to polymer clay and other materials. As the polymer clay is quite pliable and does not need to be heated and reheated to fuse it, it is a much easier medium in which to produce millefiori patterns than glass. History The manufacture of mosaic beads can be traced to Ancient Roman, Phoenician and Alexandrian times. Canes, probably made in Italy, have been found as far away as 8t ...

Glass Bead
Glass bead making has long traditions, with the oldest known beads dating over 3,000 years. Glass beads have been dated back to at least Roman times. Perhaps the earliest glass-like beads were Egyptian faience beads, a form of clay bead with a self-forming vitreous coating. Glass beads are significant in archaeology because the presence of glass beads often indicate that there was trade and that the bead making technology was being spread. In addition, the composition of the glass beads could be analyzed and help archaeologists understand the sources of the beads. Common types of glass bead manufacture Glass beads are usually categorized by the method used to manipulate the glass – wound beads, drawn beads, and molded beads. There are composites, such as millefiori beads, where cross-sections of a drawn glass cane are applied to a wound glass core. A very minor industry in blown glass beads also existed in 19th-century Venice and France. Wound glass beads Probably the earl ...

Lehr (glassmaking)
In the manufacture of float glass, a lehr oven is a long kiln with an end-to-end temperature gradient, which is used for annealing newly made glass objects that are transported through the temperature gradient either on rollers or on a conveyor belt. The annealing renders glass into a stronger material with fewer internal stresses, and with a lower probability of breaking. The rapid cooling of molten glass results in an uneven temperature distribution throughout the material. This temperature differential results in mechanical stresses throughout the molten glass, which may be sufficient to cause the material to crack as it cools to ambient temperature or to make it susceptible to cracking during later use, either spontaneously or due to mechanical or thermal shock. To prevent such material weaknesses, objects made from molten glass are annealed by gradual cooling in a lehr oven, from the annealing point, a temperature just below the solidification temperature of the glass.
