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.
Scientific glass blowing, which is practiced in some larger laboratories, is a specialized field of glassblowing. Scientific glassblowing involves precisely controlling the shape and dimension of glass, repairing expensive or difficult-to-replace glassware, and fusing together various glass parts.
Uranium glass is used as one of several intermediate glasses in what is known to scientific glass blowers as a 'graded seal'. This is typically used in glass-to-metal seals such as tungsten and molybdenum or nickel based alloys such as Kovar, as an intermediary glass between the metal sealing glass and lower expansion borosilicate glass.
Soda-lime glass is the traditional mix used in blown furnace glass, and lampworking glass rods were originally hand-drawn from the furnace and allowed to cool for use by lampworkers. Today soda-lime, or "soft" glass is manufactured globally, including Italy, Germany , Czech Republic , China and America .
From hand-worked Murano glass lamps to beveled cobalt blue vases that have been individually mouth blown, these norm-shattering glass-blown pieces are anything but derivative. Eclipse Vase
Broadly, modern glass container factories are three-part operations: the "batch house", the "hot end", and the "cold end". The batch house handles the raw materials; the hot end handles the manufacture proper—the forehearth, forming machines, and annealing ovens; and the cold end handles the product-inspection and packaging equipment.
Visitors can watch live glassmaking, [29] or learn to make glass at the museum. [30] The museum offers several live glassmaking demonstrations. [31] The Hot Glass Show is a demonstration where one of the museum's glass blowers provides a live glass-blowing demonstration, which is also narrated by another of the glass blowers.
