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. One of the most exacting and complicated caneworking techniques is "reticello", which involves creating two bubbles from cane, each twisted in a different direction and then combining them and blowing out the final form.
Lampworkers , usually but not necessarily work on a much smaller scale, historically useing 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 ancient Romans copied the technique consisting of blowing air into molten glass with a blowpipe making it into a bubble. 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. Evidence of glass blowing comes even earlier from Indian subcontinent in the form of Indo-Pacific beads which uses glass blowing to make cavity before being subjected to tube drawn technique for bead making dated more than BP.
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. Ennion for example, was among the most prominent glassworkers from Lebanon of the time. 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 the 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. Rome, the heartland of the empire, soon became a major glassblowing center, and more glassblowing workshops were subsequently established in other provinces of Italy, for example Campania , Morgantina and Aquileia. 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.
One of the most prolific glassblowing centers of the Roman period was established in Cologne on the river Rhine in Germany by late 1st century BC. 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. 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.
