WHERE GLASS İS THE WORD?

The word is used in making glass, glass powder in the past, the Latin name "glastum" estimates derived from the common name of a forest of flowers. Another approach is the "glass" of the term in English (galcede) "glas" sun "word, the meaning of the word in question lisanlardaki the" amber "is that from.

DİSCOVERY OF GLASS

Glass produced by mankind discovered and is one of the oldest materials. Until now, the archaeological excavations of the oldest glass products in the BC Belongs to 5500 years, was found in Egypt.

Centuries and centuries later is a great deal of evidence, for example, in Egypt, Pharaoh Amenotop'un glass eye. (M.Ö.4000), however, a great deal more than sonralarına findings, especially in Egypt for the years 1500 BC, which probably lived its best period in the art of glass in Egypt. Even in those times, in Egypt, cutting stone decoration, stone and glass used for polishing and glass yarn winding technique known.

This technique was later re-discovered in Venice and lived most brilliant period. Glass art in Egypt, Babylon, which is quite ileriydi neighbor. On a clay table of Babylon found the first known recipe for glass is engraved: 60 mph sand, algae and seaweed ash of 180 mph, 5 and 3 parts saltpeter measure chalk (limestone). Asur'lular first discovered the excavations can be seen in the glass.

Glass-making industry through the development of, or tile, or should have occurred naturally. Archaeological finds, Glaze and tile, and some glass beads were made from 4.binden BC, glass vessels, as the first BC Itself in the middle of the second millennium show how. In recent years, workers on this subject before the glass material from corn Hurrian-Mitanni in northern Mesopotamia, in particular claim that was made. Many construction of glass and glass-making recipe, the inscription mentions us.

The Roman writer Pliny reports the following information to us concerning the beginning of the construction of the glass. Caramel at the time of the Phoenicians in Syria (Karmelus) has an area of ??marshland called Mountain Candebia between low hills. Beginning of this swamp, and up to eight miles of the river Belus aktıktan thought then flows into the sea near the city of Ptolemais. Muddy sand deposits at the bottom of the river due to the full and very deep, but with low tide revealed. This is shaking the sand waves of mud and foreign matter temizlenirdi leave. The role of the sea water is cleaner and the impact on acılığının the sand from the sand without ever sanılırdı would not benefit. According to the rumors of a ship full of güberçile iron throws here, ship's crew on the shore preparing food they want to set up a stove to burn wood. Blocks of stone could not find any nearby ship brought güberçile make a stove. Closely with the melting of wood with sand güberçile unknown until that time, a transparent liquid sızdığını see the stove. Thus, the glass is found. We do not know if this story is true, but a plausible event. Because, wood fire, glass transition temperatures will reach the ulaşmayacağı discussed. Glass transition temperature can reach to provide suitable material has been edited, but the experiments proved. But I must not forget that the fire burned in the sand all the time everywhere, such samples must be found. Glass spent in each stage of the current state of the art of a high heat. Sample can be described by Pliny no doubt true, but even before it, that periods of ceramic glazing techniques used by masters in ceramics processing actually can be called a glass coating that is certain they know. In this mystery, a sense of the material as glass. And this is known to have been obtained as a result glassy glaze used on its own. Many of the first examples of the history of glass, ceramic, glass, showing the traces exceeded. Glass is produced artificially in nature, always had naturally. Material is actually natural glass called obsidian. Obsidian, at various times to carry the typical features of the glass, shaped in different ways. In this way, the use of tools is very common. Given such a perspective, glazing products, meaning we understand today, much earlier than the functions of an ax, a knife or the tip of the spear used as a first glazing should be considered as an example.

New York's Corning Museum of Glass araştırmacılarınca röntgenoptik the chemical and scientific research in a real sense of the glass tile "was not Egyptian tile" the development of the show could have emerged. This glass tile products, the similarity of the time period so that it is more primitive tools, appliances, furnaces, and considering the possibilities, this "tiling" of dough are cooked too long, too much sodium or to include introduction of temperatures is considered to occur at the end of the glass.

Date of origin myths in addition to scientific research, however, are found to this issue. Pilinius and had to get rocks in flavius'un. Together with fire in the past and into the river bed of incandescent kayacıkları soda combined with clean sand is hot fluid, transparent and After achieving a solid substance, have been transformed into glass.

Inanılırsa explain the origin of the glass front which is believed to be true in Asia. As a result of the excavations and research about the origin of the glass one day the truth will emerge completely final.

STRUCTURE OF GLASS

Glass is usually silicon acid; alkali or alkaline earth oxides and to a lesser extent also occurs in a mixture of coloring oxides. Glass sand, soda or potash, lime and coloring or bleaching of the substances are obtained by melting the mixture under appropriate conditions.

Silicon acid in nature kuarz sand (SiO2) is available as a. Melting point düzeylerindedir approximately 1800 degrees.

Lime (CaCO3) in nature, marble, chalk or limestone is available as a. I used to manufacture glass only burnt lime (CaO), crushed limestone kullanılıyorduysa today, no longer used. Melting point 2500 degrees düzeylerindedir lime.

These items below a certain temperature, the melting points eritebilmek catalysts are needed for a team. These catalysts are:
Soda (Na2CO3): Anhydrous sodium carbonate, also known as the melting point of 890 degrees levels of soda, carbonate known as the melting point of 890 degrees düzeylerindedir basket. Both are produced in factories. Usually the method of production of soda Solyav (ammonium carbonate salt is transmitted into the water) is performed.

    Sodium sulfate was found by r.kimyager Johann Rudolf Glauber. Sodium sulfate can be used only to melt glass. The degree of melting 900 degrees.

     Lead oxide (Pb3O4): by increasing the fragility of the glass light shine kazandırır.Camın more specific weight increases.

     Boron: increased resistance to temperature changes of the glass. (Laboratory glass, glass containers, etc. cooked meal ...)

     GİVE COLOR TO GLASS ARTİCLES

    During the construction process, yet some of the substances involved in dough depending on the percentage of glass give different shades of color. This stage of the coloring substances used were:

    Copper: Green, turquoise, red
    Chrome: Yellow, green
    Iron: Green, blue, yellow
    Copper: Green, Blue
