Natural glass in the type of obsidian was used even by Stone Age societies whose members utilized it to create sharp cutting tools. However, the archaeological evidence suggests that the initial true glass appeared somewhere in north coastal Syria, Mesopotamia or Old Kingdom Egypt. Egypt, using its preserving climate, is really a place where we could find a large amount of early glass items. Sand can be the initial man-made glass products and go back to 3500 BC. They’ve been found in Egypt and Eastern Mesopotamia. The oldest fragments of glass vases are said to originate in Mesopotamia 1600 BC. An immediate growth in glass making techniques is a member of the location recently Bronze.
With the 15th century BC, Western Asia, Crate and Egypt became extensive glass producers. They knew and safely guarded a technological key to initial fusing of glass from raw material. Glass workers in other areas of the world had access and then imported pre-formed glass forms. There exists deficiency of evidence how glass advanced between 15th and 9th century BC. Over these years glass production was centred in Alexandria. From this place it spread to Italy. The Hellenistic period brought many new techniques of glass production, and glass became to be used for making larger pieces, like table ware. During this time period, colorless and decoloured glass became valued, and methods to get it created studied in the more comprehensive way.
However, it was exactly the first century BC that brought a genuine revolution: glass blowing technique was discovered about the Syro-Palestinian coast. This method involved blowing glass inside moulds by using a long thin tube which subsequently has evolved almost no. By doing this they produced a variety of hallow glass items. Before this the entire process of setting up a small glass item was very prolonged with time; it may take several days to really make the product by casting, core forming or cutting. The introduction of glass blowing led to significant alterations in the glass making process and contributed to making glass vessels basic and inexpensive to generate. Then, ancient Romans began blowing glass inside moulds which increased shape possibilities for hollow glass items. The Romans were accountable for spreading glassmaking technology and creating foundations for developing glasswork traditions across Western Europe.
In 1271, the ban on imports of foreign glass as well as on foreign glass artists planning to are employed in Venice was introduced. In 1291 the Venetian Republic ordered the glass makers to advance their foundries to Murano. The second 50 % of the 15th century brought quartz and potash produced from sea plants on the Venetian glass making tradition. Pure crystal started to be produced. In 1688 French glass making introduced a fresh process for output of plate glass, which you can use in mirrors. The “plate pouring” process resulted in glass with good transmission qualities. The 19th century would have been a beginning of a tremendous change: glass making started evolving towards industry over the craft. Mass output of glass products was introduced along with an invention of the tank furnace by Friedrich Siemens. It allowed produce greater quantities of molten glass. Using the Twentieth century came a period of revolutionary technology. Machines were developed which replaced traditional mouth blowing which has a semi-automatic process, and transformed the craft into a market. Classical man-made glassblowing became a skill, maintaining the tradition information of ancient glassblowers. Today’s glassblower still utilizes the basic blowpipe, but now these people have a large number of supplementary tools to aid in working the pad.
