A popular movement in the 1920s and 30s, promoted by Ruhlmann and other great Paris furniture manufacturers, and the big department stores. The style was influenced by Aztec and Egyptian design, the Ballets Russes, Hollywood musicals and the new ocean-going liners. It featured stepped and geometric designs, sunrays and chevrons.

A name for streaked, white to yellowy-green, semi-transparent glass, popular in the late 19th century, as in the glass shades made by Powell's of Whitefriars. Also known as vaseline glass.

In 1925, the Societe Holophane Français, a glassworks near Rouen, expanded from making vehicle headlights into making art glass vases and bowls. They created a separate department called 'Verlys' for these works. Initially the pieces were blown vessels with several layers of glass, smooth on the outside with internal decoration. From 1933 onward, Verlys focused on high quality press-moulds. They produced clear, frosted, opalescent and colored items with designs typical of Lalique-style glass of the 1930s. In 1935, they established 'Verlys of America' in Newark, Ohio. Moulds were supplied from France for the Ohio works. Many items were produced simultaneously in France and the USA. As happened with many companies, they declined during the Second World War and changed focus to industrial products.
