Glassblowing is a glassforming technique that involves inflating molten glass into a bubble or parison with the aid of a blowpipe or blow tube.
A person who blows glass is called a glassblower , glassmith , or gaffer. A lampworker often also called a glassblower or glassworker manipulates glass with the use of a torch on a smaller scale, such as in producing precision laboratory glassware out of borosilicate glass. 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 introducing a small amount of air to it.
That is based on the liquid structure of glass where the atoms are held together by strong chemical bonds in a disordered and random network,    therefore molten glass is viscous enough to be blown and gradually hardens as it loses heat. To increase the stiffness of the molten glass, which in turn facilitates the process of blowing, there was a subtle change in the composition of glass.
With reference to their studies of the ancient glass assemblages from Sepphoris of Israel, Fischer and McCray  postulated that the concentration of natron , which acts as flux in glass, is slightly lower in blown vessels than those manufactured by casting. Lower concentration of natron would have allowed the glass to be stiffer for blowing. That allows production of blown glass with uniform thickness instead of causing blow-through of the thinned layers.
A full range of glassblowing techniques was developed within decades of its invention. This method held a pre-eminent position in glassforming ever since its introduction in the middle of the 1st century BC until the late 19th century, and is still widely used nowadays as a glassforming technique, especially for artistic purposes.
The process of free-blowing involves the blowing of short puffs of air into a molten portion of glass called a '"gather" which has been spooled at one end of the blowpipe. This has the effect of forming an elastic skin on the interior of the glass blob that matches the exterior skin caused by the removal of heat from the furnace.
The glassworker can then quickly inflate the molten glass to a coherent blob and work it into a desired shape. Researchers at the Toledo Museum of Art attempted to reconstruct the ancient free-blowing technique by using clay blowpipes. They can produce a great variety of glass objects, ranging from drinking cups to window glass.
An outstanding example of the free-blowing technique is the Portland Vase , which is a cameo manufactured during the Roman period.
An experiment was carried out by Gudenrath and Whitehouse  with the aim of re-creating the Portland Vase. A full amount of blue glass required for the body of the vase was gathered on the end of the blowpipe and was subsequently dipped into a pot of hot white glass. Inflation occurred when the glassworker blew the molten glass into a sphere which was then stretched or elongated into a vase with a layer of white glass overlying the blue body. Mold-blowing was an alternative glassblowing method that came after the invention of free-blowing, during the first part of the second quarter of the 1st century AD.
In that way, the shape and the texture of the bubble of glass is determined by the design on the interior of the mold rather than the skill of the glassworker.
Two types of molds, namely single-piece mold and multi-piece mold, are frequently used to produce mold-blown vessels. The former allows the finished glass object to be removed in one movement by pulling it upwards from the single-piece mold and is largely employed to produce tableware and utilitarian vessels for storage and transportation.
The Roman leaf beaker which is now on display in the J. Paul Getty Museum was blown in a three-part mold decorated with the foliage relief frieze of four vertical plants. The development of the mold-blowing technique has enabled the speedy production of glass objects in large quantity, thus encouraging the mass production and widespread distribution of glass objects. Glassblowing involves three furnaces. The first, which contains a crucible of molten glass, is simply referred to as the furnace.
The second is called the glory hole , and is used to reheat a piece in between steps of working with it. The final furnace is called the lehr or annealer , and is used to slowly cool the glass, over a period of a few hours to a few days, depending on the size of the pieces.
This keeps the glass from cracking or shattering due to thermal stress. Historically, all three furnaces were contained in one structure, with a set of progressively cooler chambers for each of the three purposes. The major tools used by a glassblower are the blowpipe or blow tube , punty or punty rod, pontil, or mandrel , bench, marver, blocks, jacks, paddles, tweezers, newspaper pads, and a variety of shears. The tip of the blowpipe is first preheated; then dipped in the molten glass in the furnace.
The molten glass is "gathered" onto the end of the blowpipe in much the same way that viscous honey is picked up on a honey dipper. This process, called marvering,  forms a cool skin on the exterior of the molten glass blob, and shapes it.
Then air is blown into the pipe, creating a bubble. Once a piece has been blown to its approximate final size, the bottom is finalized. The bench is a glassblower's workstation, and has a place for the glassblower to sit, a place for the handheld tools, and two rails that the pipe or punty rides on while the blower works with the piece.
Blocks are ladle-like tools made from water-soaked fruitwood , and are used similarly to the marver to shape and cool a piece in the early steps of creation. Jacks are tools shaped somewhat like large tweezers with two blades, which are used for forming shape later in the creation of a piece.
Paddles are flat pieces of wood or graphite used for creating flat spots such as a bottom. Tweezers are used to pick out details or to pull on the glass. There are two important types of shears, straight shears and diamond shears.
Straight shears are essentially bulky scissors , used for making linear cuts. Diamond shears have blades that form a diamond shape when partially open. These are used for cutting off masses of glass. There are many ways to apply patterns and color to blown glass, including rolling molten glass in powdered color or larger pieces of colored glass called frit. Complex patterns with great detail can be created through the use of cane rods of colored glass and murrine rods cut in cross-sections to reveal patterns.
These pieces of color can be arranged in a pattern on a flat surface, and then "picked up" by rolling a bubble of molten glass over them. A lampworker , usually operating on a much smaller scale, historically used alcohol lamps and breath or bellows -driven air to create a hot flame at a workbench to manipulate preformed glass rods and tubes.
These stock materials took form as laboratory glassware , beads, and durable scientific "specimens"—miniature glass sculpture. The craft, which was raised to an art form in the late s by Hans Godo Frabel later followed by lampwork artists such as Milon Townsend and Robert Mickelson , is still practiced today.
The modern lampworker uses a flame of oxygen and propane or natural gas. The modern torch permits working both the soft glass from the furnace worker and the borosilicate glass low-expansion of the scientific glassblower. This latter worker may also have multiple headed torches and special lathes to help form the glass or fused quartz used for special projects.
The earliest evidence of glassblowing was found by Roman Ghirshman in Chogha Zanbil , where many glass bottles were found in the excavations of the 2nd millennium BC site.
Hence, tube blowing not only represents the initial attempts of experimentation by glassworkers at blowing glass, it is also a revolutionary step that induced a change in conception and a deep understanding of glass. The invention of glassblowing coincided with the establishment of the Roman Empire in the 1st century BC, which enhanced the spread and dominance of this new technology.
He was renowned for producing the multi-paneled mold-blown glass vessels that were complex in their shapes, arrangement and decorative motifs. Mold-blown glass vessels manufactured by the workshops of Ennion and other contemporary glassworkers such as Jason, Nikon, Aristeas, and Meges, constitutes some of the earliest evidence of glassblowing found in the eastern territories.
Eventually, the glassblowing technique reached Egypt and was described in a fragmentary poem printed on papyrus which was dated to 3rd century AD. Later, the Phoenician glassworkers exploited their glassblowing techniques and set up their workshops in the western territories of the Roman Empire, first in Italy by the middle of the 1st century AD.
From there, escaping craftsmen who had been forbidden to travel otherwise advanced to the rest of Europe by building their glassblowing workshops in the north of the Alps which is now Switzerland , and then at sites in northern Europe in present-day France and Belgium. Stone base molds and terracotta base molds were discovered from these Rhineland workshops, suggesting the adoption and the application of mold-blowing technique by the glassworkers.
Surviving physical evidence, such as blowpipes and molds which are indicative of the presence of blowing, is fragmentary and limited. Pieces of clay blowpipes were retrieved from the late 1st century AD glass workshop at Avenches in Switzerland.
The glass blowing tradition was carried on in Europe from the medieval period through the Middle Ages to the Renaissance in the demise of the Roman Empire in the 5th century AD. During the early medieval period, the Franks manipulated the technique of glassblowing by creating the simple corrugated molds and developing the claws decoration techniques. The Byzantine glassworkers made mold-blown glass decorated with Christian and Jewish symbols in Jerusalem between late 6th century and the middle of the 7th century AD.
Renaissance Europe witnessed the revitalization of glass industry in Italy. Glassblowing, in particular the mold-blowing technique, was employed by the Venetian glassworkers from Murano to produce the fine glassware which is also known as cristallo. The " studio glass movement " began in when Harvey Littleton , a ceramics professor, and Dominick Labino , a chemist and engineer, held two workshops at the Toledo Museum of Art , during which they started experimenting with melting glass in a small furnace and creating blown glass art.
Littleton promoted the use of small furnaces in individual artists studios . This approach to glassblowing blossomed into a worldwide movement, producing such flamboyant and prolific artists as Dale Chihuly , Dante Marioni , Fritz Driesbach and Marvin Lipofsky as well as scores of other modern glass artists.
Today there are many different institutions around the world that offer glassmaking resources for training and sharing equipment. Working with large or complex pieces requires a team of several glassworkers, in a complex choreography of precisely timed movements. This practical requirement has encouraged collaboration among glass artists, in both semi-permanent and temporary working groups.
The writer Daphne du Maurier was descended from a family of glass-blowers in 18th century France, and she wrote about her forebears in the historical novel The Glass-Blowers. The subject of mystery novelist Donna Leon 's Through a Glass, Darkly is the investigation of a crime in a Venetian glassworks on the island of Murano.
