The Art Of Glass

Glass art and glass sculpture is the use of glass as an artistic medium to produce sculptures or two-dimensional artworks. Specific approaches include stained glass, working glass in a torch flame (lampworking), glass beadmaking, glass casting, glass fusing, and, most notably, glass blowing. As a decorative and functional medium, glass was extensively developed in Egypt and Assyria, brought to the fore by the Romans (who spread glassblowing, invented by the Phoenicians), and includes among its greatest triumphs European cathedral stained glass windows. Great ateliers like Tiffany, Lalique, Daum, Gallé, the Corning schools in upper New York state, and Steuben Glass Works took glass art to the highest levels. Glass from Murano (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 art.

The glass objects created are intended to make a sculptural or decorative statement. On the market, their prices may range from a few hundred to tens of thousands of dollars (US).

Prior to the early 1960s, the term "glass art" referred to glass made for decorative use, usually by teams of factory workers, taking glass from furnaces with a thousand or more pounds of glass. This form of glass art, of which Tiffany and Steuben in the U.S.A., Gallé in France and Hoya Crystal in Japan, Royal Leerdam Crystal in The Netherlands and Orrefors andKosta Boda in Sweden are perhaps the best known, grew out of the factory system in which all glass objects were hand or mold blown by teams of 4 or more men. The turn of the 19th Century was the height of the old art glass movement while the factory glass blowers were being replaced by mechanical bottle blowing and continuous window glass.

The evil eye is a belief that the envy elicited by the good luck of fortunate people may result in their misfortune. The perception of the nature of the phenomenon causes, possible protective measures, varies between different cultures.

Glassblowing is a glassforming technique that involves inflating the molten glass into a bubble, or parison, with the aid of the blowpipe, or blow tube. A person who blows glass is called a glassblower, glassmith, or gaffer.

The term stained glass can refer to the material of coloured glass or the craft of working with it. Throughout its thousand-year history, the term "stained glass" has been applied almost exclusively to the windows of churches, cathedrals, chapels, and other significant buildings. Although traditionally made in flat panels and used as windows, the creations of modern stained glass artists also include three-dimensional structures and sculpture.

Modern vernacular usage has often extended the term "stained glass" to include domestic leadlight and objets d'art created from lead came and copper foil glasswork such as exemplified in the famous lamps of Louis Comfort Tiffany.

As a material stained glass is glass that has been coloured by adding metallic salts during its manufacture. The coloured glass is crafted into stained glass windows in which small pieces of glass are arranged to form patterns or pictures, held together (traditionally) by strips of lead and supported by a rigid frame. Painted details and yellow stain are often used to enhance the design. The term stained glass is also applied to windows in which the colours have been painted onto the glass and then fused to the glass in a kiln.

Stained glass, as an art and a craft, requires the artistic skill to conceive an appropriate and workable design, and the engineering skills to assemble the piece. A window must fit snugly into the space for which it is made, must resist wind and rain, and also, especially in the larger windows, must support its own weight. Many large windows have withstood the test of time and remained substantially intact since the late Middle Ages. In Western Europe they constitute the major form of pictorial art to have survived. In this context, the purpose of a stained glass window is not to allow those within a building to see the world outside or even primarily to admit light but rather to control it. For this reason stained glass windows have been described as 'illuminated wall decorations'.

The design of a window may be non-figurative or figurative; may incorporate narratives drawn from the Bible, history, or literature; may represent saints or patrons, or use symbolic motifs, in particular armorial. Windows within a building may be thematic, for example: within a church - episodes from the life of Christ; within a parliament building - shields of the constituencies; within a college hall - figures representing the arts and sciences; or within a home - flora, fauna, or landscape.

Technically, the term crystal should never be applied to glass, as glass, by definition, lacks a crystalline structure. The use of the term lead crystal remains popular due to historical and commercial reasons; originally stemming from the Venetian use of the word cristallo to describe the rock crystal imitated by Murano glassmakers. This is a naming convention which has been maintained to the present day to describe decorative hollowware.
