A stage in the manufacture of a Bristol blue glass ship's decanter.The blowpipe is being held in the glassblower's left hand. The glass is glowing yellow. As a novel glass forming technique created in the middle of the 1st century BC, glassblowing exploited a working property of glass that was previously unknown to glassworkers; inflation, which is the expansion of a molten blob of glass by ...
In 1891 Libbey opened a new plant in Findlay, Ohio, and Owens was put in charge of making the glass bulbs for Edison General Electric’s electric lights. There he simplified the process by inventing a mould-opening device which could be operated by a glassblower by foot and came up with a paste that prevent the bulbs from sticking to the moulds.
Evidence of the use of the blown plate glass method dates back to 1620 in London and was used for mirrors and coach plates. Louis Lucas de Nehou and A. Thevart perfected the process of casting polished plate glass in 1688 in France. Prior to this invention, mirror plates, made from blown "sheet" glass, had been limited in size.
Until the 20th century, window glass production involved blowing a cylinder and flattening it. [9] Two major methods to make window glass, the crown method and the cylinder method, were used until the process was changed much later in the 1920s. [10] All glass products must then be cooled gradually , or else they could easily break. [11]
In glassblowing, the term blowpipe refers to a pipe used to blow a bubble of air into a gather of molten glass, as the first step in the creation of hand-blown glass bottles and bowls. By the end of the first century, the two primary glassblowing tools were the iron blowpipe and pontil . [ 2 ]
Between 1820 and 1840, one hundred glass factories are known to have been in operation in the U.S. [16] It is known from descriptions in advertisements and invoices that the Boston and Sandwich Glass Company and the New England Glass Company were major producers of blown three-mold glass. [13] Most colorless glass was made by the New England ...
When the glass cooled off, the clay was chipped out of the inside leaving just the hollow glass vessel. [3] This glass was very thin as the fire was not as hot as modern-day furnaces. The blowpipe was invented around 1 B.C. This allowed molten glass to be gathered on the end of the blow pipe and blown into the other end to create a hollow vessel.
Harvey Kline Littleton was born in Corning, New York, the fourth offspring of Dr. Jesse T. Littleton Jr., and Bessie Cook Littleton.His father was a physicist who had been recruited from the faculty at the University of Michigan to join the first research team at Corning Glass Works.
