The simplest cane, called vetro a fili [3] (glass with threads) is clear glass with one or more threads of colored (often white) glass running its length. It is commonly made by heating and shaping a chunk of clear, white, or colored glass on the end of a punty, and then gathering molten clear glass over the color by dipping the punty in a ...
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 ...
Scientific glassblowing is a specialty field of lampworking used in industry, science, art and design used in research and production. Scientific glassblowing has been used in chemical, pharmaceutical, electronic and physics research including Galileo's thermometer, Thomas Edison's light bulb, and vacuum tubes used in early radio, TV and computers.
Ziemke began glassblowing while a student at Pennsylvania State University in 1976. [1] After graduating in 1978, he served a one-year apprenticeship. The following year, he opened his first studio in Accord, New York. [2]
However, in Local No. 106, Glass Bottle Blowers Association, AFL–CIO (Owens-Illinois, Inc.) and Local No. 245, Glass Bottle Blowers Association, AFL–CIO (Owens-Illinois, Inc.) 210 NLRB 943 (1974), the National Labor Relations Board ruled that gender-segregated locals violated the right of workers to elect representatives of their own ...
The ancient technique of blown glass, where a glassblower works at a furnace full of molten glass using metal rods and hand tools to blow and shape almost any form of glass, is one of the more popular ways to work. Most large hollow pieces are made this way, and it allows the artist to be improvisational as they create their work.
1887, a new glass factory was built in Muncie, Indiana; metal manufacturing operations continued at Buffalo and Bath, New York [3] 1889, the company's metal fittings operations were moved to Muncie [3] 1897, F. C. Ball Machine, the world's first semiautomatic glass machine, was invented (U.S. patent number 610515, issued in 1898) [37] [38]
Warm glass is rolled on the marver, both to shape it and as a means of temperature control. [3] With a high specific heat capacity , the surface absorbs heat from the glass; because of the relatively slow flow of heat through the glass, it does so particularly from the outermost material, forming a more viscous skin.
