Vitreous marble

Vitrolite was an opaque pigmented glass manufactured by Pilkington Brothers in the United Kingdom. It was made by The Vitrolite Company (1908–1935) and Libbey-Owens-Ford (1935–1947) in the United States.

The same structural pigmented glass was marketed as Sani Onyx (or Rox) by the Marietta Manufacturing Company from 1900 onward and as Carrara Glass by the Penn-American Plate Glass Company after 1906. The latter brand is named for the white or blue-grey Carrara marble, a structural veneer from Carrara, Tuscany, Italy for which the pigmented structural glass represented a lower-cost alternative.

The term vitreous marble was used by Marietta Manufacturing as a generic identifier for pigmented structural glass, although the genericised trademarks are in common use.

The introduction to Vitrolite Specification, published in 1938 by Pilkington Brothers, stated that Vitrolite was a rolled opal glass, ranging from semi-opacity to complete opacity. One surface was usually impressed with a pattern of narrow parallel ribs which provide a key for the mastic or other material with which the glass is fixed. The glass had a hard, brilliant, fire-finished surface.

Carrara

Carrara [karˈraːra] (Emilian: Carara) is a city and comune in the Province of Massa and Carrara (Tuscany, Italy), notable for the white or blue-grey marble quarried there. It is on the Carrione River, some 100 kilometres (62 mi) west-northwest of Florence.

Its motto is Fortitudo mea in rota (Latin: "My strength is in the wheel").

History

There were known settlements in the area as early as the 9th century BC, when the Apuan Ligures lived in the region. The current town originated from the borough built to house workers in the marble quarries created by the Romans after their conquest of Liguria in the early 2nd century BC. Carrara has been linked with the process of quarrying and carving marble since the Roman Age. Marble was exported from the nearby harbour of Luni at the mouth of river Magra.

In the Middle Ages it was a Byzantine and Lombard possession, and then, it was under bishops of Luni, turning itself into an city-state in the early 13th century; during the struggle between Guelphs and Ghibellines, Carrara usually belonged to the latter party. The Bishops acquired it again in 1230, their rule ending in 1313, when the city was given in succession to the Republics of Pisa, Lucca and Florence. Later it was acquired by Gian Galeazzo Visconti of Milan.
