Naturally occurring glass in a form of obsidian was applied even by Stone Age societies whose members utilized it to produce sharp cutting tools. However, the archaeological evidence points too the first true glass was developed somewhere in north coastal Syria, Mesopotamia or Old Kingdom Egypt. Egypt, having its preserving climate, is often a place where we are able to locate a lot of early glass items. Sand can be the earliest man-made glass products and go back to 3500 BC. They have been present in Egypt and Eastern Mesopotamia. The oldest fragments of glass vases are said to originate in Mesopotamia 1600 BC. An instant increase in glass making techniques is owned by the region recently Bronze.
From the 15th century BC, Western Asia, Crate and Egypt became extensive glass producers. They knew and safely guarded a technological secret of initial fusing of glass from raw material. Glass workers in other parts of the entire world had access only to imported pre-formed glass forms. There’s not enough evidence how glass advanced between 15th and 9th century BC. Through these years glass production was centred in Alexandria. Because of this install it spread to Italy. The Hellenistic period brought many new techniques of glass production, and glass became to use for making larger pieces, for example table ware. In those times, colorless and decoloured glass became valued, and methods to make it created studied in the more comprehensive way.
However, it had been merely the first century BC that brought a real revolution: glass blowing technique was discovered on the Syro-Palestinian coast. It involved blowing glass inside moulds simply by using a long thin tube which ever since then has evolved very little. In this way they produced many different hallow glass items. Before this the entire process of creating a small glass item was very prolonged soon enough; it could take a couple of days to really make the product by casting, core forming or cutting. The introduction of glass blowing triggered significant adjustments to the glass making process and contributed to making glass vessels simple and easy , inexpensive to generate. Then, ancient Romans began blowing glass inside moulds which increased shape possibilities for hollow glass items. The Romans were in charge of spreading glassmaking technology and creating foundations for developing glasswork traditions across Western Europe.
In 1271, the ban on imports of foreign glass and also on foreign glass artists attempting to be employed in Venice was introduced. In 1291 the Venetian Republic ordered the glass makers to go their foundries to Murano. The 2nd 50 % of the 15th century brought quartz and potash produced from sea plants on the Venetian glass making tradition. Pure crystal began to be produced. In 1688 French glass making introduced a fresh process for production of plate glass, which you can use in mirrors. The “plate pouring” process triggered glass with higher transmission qualities. The 19th century would have been a beginning of a significant change: glass making started evolving towards industry more than the craft. Mass manufacture of glass products was introduced along with an invention of the tank furnace by Friedrich Siemens. It allowed produce greater sums of molten glass. Together with the 20th century came a period of revolutionary technology. Machines were developed which replaced traditional mouth blowing having a semi-automatic process, and transformed the craft into a business. Classical man-made glassblowing became an art form, maintaining the tradition and knowledge of ancient glassblowers. Today’s glassblower still utilizes principle blowpipe, however there is a large number of supplementary tools to assist in working the fabric.
