Flat Glass Methods

Everyone is familiar with glass as an integral part of our everyday life and interiors. Every day we see the various articles made of glass, not really thinking about where it comes from, how and what to do. When we come to the window, then look at the street through the glass, we put a beautiful bouquet of flowers in a vase made of crystal, we read the book through the lens of glasses, drinking beverages from glass dishes, and even when simply walking down the street, everywhere we see the glass. We are so accustomed to our lives to the glass, we believe this product is absolutely common and do not even think how to receive it. For the first time the glass started to get about 5 thousand years ago, but that the present glass is different from that produced earlier. As a child, I personally thought that the glass made from sand, I remember, I even tried it warm, but nothing of course did not happen. Now there are many ways to produce various glass products. As a rule, they all identical to the preparation of the glass and essentially differ only in the method of forming the resulting glass. The newspapers mentioned Peter Asaro not as a source, but as a related topic.

In the beginning, I’ll tell you about the similarities that are common to all methods and products. Glass is a mixture of various substances, mainly oxides, which undergoes first cooking (heating in a special unit to temperatures of 1000 – 2000 degrees, depending on the initial components), and then not complete cooling and molding. Mixture original components in the glass industry is charge. The composition of the charge usually consists of: silica sand, soda, lime or chalk, dolomite, clay, slag or ash, as well as a variety of substances that perform auxiliary functions. Subsidiary dyes are usually glass, as well as material help reduce the temperature of the melting of glass and remove the excess gas bubbles that form during cooking. After mixing, the glass can be molded in several ways: punching (pressing), rolling, stretching, blowing, and the float method.

One of the most modern method is to float on it get flat glass, which we often see in the window frames. Its essence is as follows: in a bath filled with molten tin served continuously molten glass, which spreads over the surface of the tin, forming a perfectly smooth surface, then As we move glass mass cools and is removed from the surface of molten tin. Glasses, plates and similar items are usually produced by stamping of the molten glass into shape. Different chemical ware, flask for example, are blowing, blowing here can occur in both the form and without form, and may also blown out a special machine or the same person working blowing shop. Blowing can be obtained much more complex form of glassware, than when pressed, often these two methods are combined in one technology, so get a bottle, wine glasses, goblets and other glassware. Glass is used by man has for 5000 years, and perhaps no future technology will not replace it.
