Tiffany glass

In 1865, Tiffany traveled to Europe, and in London he visited the Victoria and Albert Museum, whose extensive collection of Roman and Syrian glass made a deep impression on him.

The favrile, or "fabrile" glass was manufactured at the Tiffany factory located at 96–18 43rd Avenue in the Corona section of Queens[9] from 1901 to 1932.

Tiffany's glass fell out of favor in the 1910s, and by the 1920s a foundry had been installed for a separate bronze company.

Ownership of the complex passed back to the original owners of the factory — the Roman Bronze Works — which had served as a subcontractor to Tiffany for many years.

The first type is exemplified by blue-tinged semi-opaque or clear glass with milky opalescence in the center, seen in creations by Lalique, Sabino, and Jobling's.

Many French companies in the 1920s and 1930s, such as Lalique and Sabino, produced opalescent art deco pieces.

The second type features a milky white edge or raised pattern on colored pressed glass.

This method was employed by various companies, including Barolac in Bohemia, Joblings in England, and Val St Lambert in Belgium.

The third type involves hand-blown glass with two layers, containing heat-reactive components like bone ash.

These hand-stretched streamers are pressed on the molten surface of sheet glass during the rolling process, and become permanently fused.

These hand blown shards are pressed on the surface of the molten glass sheet during the rolling process, to which they become permanently fused.

Tiffany made use of such textured glass to represent, for example, twigs, branches and grass, and distant foliage.

When Tiffany Studio closed in 1929–1930,[3][1][2][4] the secret formula for making ring mottle glass was forgotten and lost.

[12] Traditionally used for organic details on leaves and other natural elements, ring mottles also find a place in contemporary work when abstract patterns are desired.
