History of Glass Vases:|
Glass Vases is defined by webster as: a vessel that is used chiefly as an ornament or for holding flowers that generally are made of various amorphous materials formed from a melting by cooling to rigidity without crystallization: a usually transparent or translucent material consisting typically of a mixture of silicates. The making of the glass vases and and the usage has been around for centuries. As people's appreciation for floristry increase, the usage of vase becomes more and more common. In the recent days, the glass vases are used for various decoration purposes of events. Many of artists and designers often use clear glass vases to decorate a surrounding that are able to make a empty and listless room into a festive and lively place for events. Clear glass vases are like a blank canvas to artists, they are able to turn it into something that are artistic and elegant. Florists work with flowers and plants and bring the floral art into everyday life. Floral arts is the art of creating flower arrangements in vases, bowls and baskets, or making bouquets and compositions from cut flowers, foliage, herbs, ornamental grasses and other botanical materials.
Glass Vases's history can be traced back to the great Stone Age. It was found as a obsidian - naturally occuring glass.
"The tradition is that a merchant ship laden with nitrum being moored at this place, the merchants were preparing their meal on the beach, and not having stones to prop up their pots, they used lumps of nitrum from the ship, which fused and mixed with the sands of the shore, and there flowed streams of a new translucent liquid, and thus was the origin of glass."
During the Late Bronze Age in Egypt and Western Asia there was an explosion in glass-making technology. Archaeological finds from this period include coloured glass ingots, vessels (often coloured and shaped in imitation of highly prized wares of semi-precious stones) and the ubiquitous beads. The alkali of Syrian and Egyptian glass was soda ash, sodium carbonate, which can be extracted from the ashes of many plants, notably halophile seashore plants: (see saltwort). The earliest vessels were 'core-wound', produced by winding a ductile rope of metal round a shaped core of sand and clay over a metal rod, then fusing it with repeated reheatings. Threads of thin glass of different colours made with admixtures of oxides were subsequently wound around these to create patterns, which could be drawn into festoons with a metal raking tools. The vessel would then be rolled flat ('marvered') on a slab in order to press the decorative threads into its body. Handles and feet were applied separately. The rod was subsequently allowed to cool as the glass slowly annealed and was eventually removed from the centre of the vessel, after which the core material was scraped out. Glass shapes for inlays were also often created in moulds. Much early glass production, however, relied on grinding techniques borrowed from stone working. This meant that the glass was ground and carved in a cold state.
By the 15th century BC extensive glass production was occurring in Western Asia and Egypt.
Glass remained a luxury material, and the disasters that overtook Late Bronze Age civilisations seem to have brought glass-making to a halt. It picked up again in its former sites, in Syria and Cyprus, in the ninth century BC, when the techniques for making colourless glass were discovered. In Egypt glass-making did not revive until it was reintroduced in Ptolemaic Alexandria. Core-formed vessels and beads were still widely produced, but other techniques came to the fore with experimentation and technological advancements. During the Hellenistic period that colourless or decoloured glass began to be prized and methods for achieving this effect were investigated more fully.
During the first century BC glass blowing was discovered on the Syro-Palestinian coast, revolutionising the industry and laying the way for the explosion of glass production that occurred throughout the Roman world. Over the next 1000 years glass making and working continued and spread through southern Europe and beyond.
During the Roman Empire craftsmen working as non-citizens developed many new techniques for the creation of glass. Through conquest and trade, the use of glass objects and the techniques used for producing them were spread as far as Scandinavia, the British Isles and China. This spreading of technology resulted in glass artists congregating in areas such as Alexandria in Egypt where the famous Portland Vase was created, the Rhine Valley where Bohemian glass was developed and to Byzantium where glass designs became very ornate and where processes such as enamelling, staining and gilding were developed. At this time many glass objects, such as seals, windows, pipes, and vases were manufactured. Early examples of window glass found in Karanis, Egypt were translucent and very thick . When the Emperor Constantine moved to Byzantium the use of glass continued, and spread to the Islamic world, the masters of glass-vessel making in the later Middle Ages. However, in Europe, the use of glass declined and many techniques were forgotten. The production of glass did not completely stop; it was used throughout the Anglo-Saxon period in Britain. But it did not become common again in the West until its resurgence in the 7th century.
In the medieval Islamic world, the first clear, colourless, high-purity glasses were produced by Muslim chemists, architects and engineers in the 9th century. Examples include Silica glass and colourless high-purity glass invented by Abbas Ibn Firnas (810-887), who was the first to produce glass from sand and stones. The Arab poet al-Buhturi (820-897) described the clarity of such glass, "Its colour hides the glass as if it is standing in it without a container."
Beginning in the late 20th century, glass started to become highly collectable as art. Works of art in glass can be seen in a variety of museums, including the Chrysler Museum, the Museum of Glass in Tacoma, the Metropolitan Museum of Art, the Toledo Museum of Art, and Corning Museum of Glass, in Corning, NY, which houses the world's largest collection of glass art and history, with more than 45,000 objects in its collection.
Several of the most common techniques for producing glass art include: blowing, kiln-casting, fusing, slumping, pate-de-verre, flame-working, hot-sculpting and cold-working. Cold work includes traditional stained glass work as well as other methods of shaping glass at room temperature. Glass can also be cut with a diamond saw, or copper wheels embedded with abrasives, and polished to give gleaming facets; the technique used in creating waterford crystal . Art is sometimes etched into glass via the use of acid, caustic, or abrasive substances. Traditionally this was done after the glass was blown or cast. In the 1920s a new mould-etch process was invented, in which art was etched directly into the mould, so that each cast piece emerged from the mould with the image already on the surface of the glass. This reduced manufacturing costs and, combined with a wider use of colored glass, led to cheap glassware in the 1930s, which later became known as Depression glass. As the types of acids used in this process are extremely hazardous, abrasive methods have gained popularity.
Objects made out of glass include not only traditional objects such as vessels (bowls, vases, bottles, and other containers), paperweights, marbles, beads, smoking pipes, bongs, but an endless range of sculpture and installation art as well. Colored glass is often used, though sometimes the glass is painted, innumerable examples exist of the use of stained glass.
