History of glass
Glass remained a luxury material, and the disasters that overtook Late Bronze Age civilizations seem to have brought glass-making to a halt. It picked up again in its former sites, Syria and Cyprus, in the 9th century BC, when the techniques for making colorless glass were discovered. The first glassmaking "manual" dates back to ca. 650 BC. Instructions on how to make glass are contained in cuneiform tablets discovered in the library of the Assyrian king Ashurbanipal. In Egypt glass-making did not revive until it was reintroduced in Ptolemaic Alexandria. Core-formed vessels and beads were still widely produced, but other techniques came to the fore with experimentation and technological advancements. During the Hellenistic period many new techniques of glass production were introduced and glass began to be used to make larger pieces, notably table wares. Techniques developed during this period include 'slumping' viscous (but not fully molten) glass over a mould in order to form a dish and 'millefiori' (meaning 'thousand flowers') technique, where canes of multicolored glass were sliced and the slices arranged together and fused in a mould to create a mosaic-like effect. It was also during this period that colorless or decolored glass began to be prized and methods for achieving this effect were investigated more fully.
Early glassmaking in the United States
The style of glassmaking changed by 1746 when the government passed the Glass Excise Bill, which taxed glass by weight; beginning in 1751 advertisements in a Boston newspaper made a reference to “new fashion” glass. Usually the phrase referred to the air twist stemmed glass or “wormed wine glasses” that had first been advertised in the Boston market in 1746. By 1761, glasses and decanters were also engraved or “flowered”. Glassmakers worked diligently to provide special glasses for specific purposes, and inevitably only the well-to-do could afford a full array of forms. The inventory of Governor Francis Fauquier’s glass is revealing, when the former Governor of Virginia died in 1768, he left: 5 beer glasses, 5 champagne glasses, 14 water glasses, 55 wine glasses, 59 syllabub glasses, 69 jelly glasses, 23 glass salvers, 15 decanters and 8 cruets. He also had three sets of salvers that made up into large pyramids; the largest pyramid was valued at £15. Such pyramids were advertised in the Boston press in 1772.
During the Federal Period, after the American Revolutionary War, Americans adopted new European styles. During the Revolutionary period, decoration was minimal. Although the American glass industry was making a strong beginning, considerable quantities were still imported. Cut glass was advertised in Baltimore as early as 1786, gaining popularity toward the end of the period. American production of blown three-mold glass began during the War of 1812. Glassmakers Henry William Stiegel and John Frederick Amelung had both tried to produce elaborate, fine table glass rivaling the European imports and both failed because there was not yet a market for the work they produced.
