Glass art is usually understood to refer to large modern works of art, typically one-off creations, which are substantially or wholly made in glass. It is distinguished from "art glass" and "studio glass" which are typically smaller and often made in editions of many identical pieces, but the boundaries are not clear-cut. Glass art is more likely to be exhibited in public spaces rather than in homes.

Artistically decorated, individually commissioned, large glass panels are usually for interior use, often in hotels, cruise liners and restaurants or night clubs. The decorative techniques used would include wheel carving, engraving, frosting, acid-etching, enamelling and gilding (including Angel gilding), often combining techniques by the use of masking or silkscreening.

A very large artwork consisting of several sections to make up the whole.

Example:

A huge installation measuring 20x20x80 feet made up of glass capillary tubes. The work was shown at L’Espace Duchamp Villon, Rouen, France.

A suite of three large scale sculptures in Lincoln House office tower, Hong Kong, by Warren Carther, Canadian Architectural Glass Artist. At twenty five tons, and collectively spanning over 50 meters the immense pieces of the trilogy each represent a particular facet of time: the past, the present, and the future.

Glass is an amorphous (non-crystalline) solid material. Glasses are typically brittle and optically transparent.

The most familiar type of glass, used for centuries in windows and drinking vessels, is soda-lime glass, composed of about 75% silica (SiO₂) plus Na₂O, CaO, and several minor additives. Often, the term glass is used in a restricted sense to refer to this specific use.

In science, however, the term glass is usually defined in a much wider sense, including every solid that possesses a non-crystalline (i.e., amorphous) structure and that exhibits a glass transition when heated towards the liquid state. In this wider sense, glasses can be made of quite different classes of materials: metallic alloys, ionic melts, aqueous solutions, molecular liquids, and polymers. For many applications (bottles, eyewear) polymer glasses (acrylic glass, polycarbonate, polyethylene terephthalate) are a lighter alternative to traditional silica glasses.

Silica (the chemical compound SiO₂) is a common fundamental constituent of glass. In nature, vitrification of quartz occurs when lightning strikes sand, forming hollow, branching rootlike structures called fulgurite.

Art is a term that describes a diverse range of human activities and the products of those activities, but is most often understood to refer to painting, film, photography, sculpture, and other visual media. Music, theatre, dance, literature, and interactive media are included in a broader definition of art or the arts. Until the 17th century, art referred to any skill or mastery and was not differentiated from crafts or sciences, but in modern usage the fine arts are distinguished from acquired skills in general.

Many definitions of art have been proposed by philosophers and others who have characterized art in terms of mimesis, expression, communication of emotion, or other values. During the Romantic period, art came to be seen as "a special faculty of the human mind to be classified with religion and science".

The nature of art, and related concepts such as creativity and interpretation, are explored in a branch of philosophy known as aesthetics.

The Encyclopædia Britannica Online defines art as "the use of skill and imagination in the creation of aesthetic objects, environments, or experiences that can be shared with others". By this definition of the word, artistic works have existed for almost as long as humankind: from early pre-historic art to contemporary art; however, some theories restrict the concept to modern Western societies. The first and broadest sense of art is the one that has remained closest to the older Latin meaning, which roughly translates to "skill" or "craft." A few examples where this meaning proves very broad include artifact, artificial, artifice, medical arts, and military arts. However, there are many other colloquial uses of the word, all with some relation to its etymology.
