Technical Description
A rare example of Thomas Webb 'Brian' glass in the form of a vase. Lipped and tapered form with superb iridescence. Sits on a circular foot with a polished pontil. The process called for the use of a closed muffle or chamber where the fumes from the evaporation of tin and other metallic salts permanently attached to the surface of the glass producing a rainbow of iridescent blues, purples and green colours. Very experimental for its time.

Historical Relevance
During July 1880, the French-American Union announces that enough money has been raised to complete the construction of the Statue of Liberty, although further funding will be required to construct the pedestal on which it will sit in New York Harbor.
