Early American molded glass

The Americans developed machinery for pressing glass in the early 19th century,and English glass-makers were producing pressed glass by the ‘s. Pressed glass older than the ‘s is now rare. Before gas and electricity were introduced, oil lamps with glass chimneys were widely used, and there was a huge demand for replacement glass chimneys.

George Davidson founded one of the most successful and prolific glass factories in England in response to this demand. In , at the age of 45, he decided that there was such a shortage of oil lamp chimneys he would build a glass factory in the nearby Team Valley.

These are caused by variations in the mixtures of glass and would change over the years for cost or other reasons. With a lot of work it is possible that some guidance to dating can be given. Ideally information from the workers in the factories on the formulae used would be a start. Otherwise it is a case of tabulating the different designs and tints found It would not be an exact science as of course over the years similar tints could appear again.

The war would of course be a significant factor in changing the sources of materials and thus the need to change formulae.

Nineteenth-century American glassmakers experimented with new methods to create products for a growing consumer market. In the s, pressing glass into metal molds by machine was perfected, and by the mids, manufacturers were creating a variety of inexpensive pressed glass housewares.

Common blown molded tableware items bearing designs include salt dishes, sugar bowls , creamers , celery stands, decanters, and drinking glasses.

Undecorated bottles used as containers for a variety of liquids were blown into square molds to give them corners so they could be packed into compartments of wooden cases. After the War of , American glass manufacturers began using molds as an inexpensive way to produce glassware similar in appearance to the very costly cut glass that was imported from Waterford, Ireland.

The process of blowing molten glass into a mold made of clay is known to have been employed in Syrian workshops as early as the 4th century BCE. Although no intact molds have been found, fragments of molds have been excavated at glass manufacturing sites in Sandwich, Massachusetts and Kent and Mantua, Ohio.

Use of the hand press continued until about and overlapped with the development of more sophisticated pressing techniques. The bench press, invented around or and used until about , was the first pressing mechanism to use a lever to force glass into a mold.

Small forms such as furniture knobs, salts and cup plates could be made in the bench press. Union Glass Works in Kensington was one of the first companies to use this technology.
