Glass art refers to individual works that are substantially or wholly made out of glass. These can range in size from very large works and installations, wall and window hangings and lighting, to works of art, including studio glass and glass jewellery.

Techniques are also varied and range from traditional copper foil (think Tiffany lamps), leaded stained glass windows, kiln formed glass of fused and slump work, to cast and hot glass created by glass blowers, a tradition for which Murano near Venice is world famous.

Metals frequently used in artwork include bronze, gold, silver, copper and aluminium. Metal can be used either as an embellishment to an artwork created in another medium or as the main substrate for an artwork which is applied to it, embedded into it or cast from it. For example, photographer Juliette Scott creates one of originals of her photographs by printing onto copper and gold surfaces.

Similar to metal, wood can be the artwork itself or it can be the vehicle used to create or present an artwork. For example, Julia Desch creates tactile textiles which are applied onto wooden wheels for presentation, and printmakers often use wood as the block from which to print.
