Antique Viennese Art Deco Bronze of Female Dancer by Bruno Zach c 1920 20th C

Art Deco or Deco,
is an influential visual arts design style which first appeared in France during the 1920s, flourished internationally during the 30s and 40s.

It is an eclectic style that combines traditional craft motifs with Machine Ageimagery and materials. The style is often characterized by rich colours, bold geometric shapes, and lavish ornamentation.

Deco emerged from the Interwar period when rapid industrialization was transforming culture. One of its major attributes is an embrace of technology. This distinguishes Deco from the organic motifs favored by its predecessor Art Nouveau.

Historian Bevis Hillier defined Art Deco as "an assertively modern style...[that] ran to symmetry rather than asymmetry, and to the rectilinear rather than the curvilinear; it responded to the demands of the machine and of new material...[and] the requirements of mass production".

During its heyday Art Deco represented luxury, glamour, exuberance, and faith in social and technological progress.

Lost Wax Method
sometimes called by the French name of cire perdue or the Latin, cera perduta is the process by which a bronze or brass is cast from an artists sculpture.

In industrial uses, the modern process is called investment casting. An ancient practice, the process today varies from foundry to foundry, but the steps which are usually used in casting small bronze sculptures in a modern bronze foundry are generally quite standardised.
