In a series of great discoveries, such as the invention of the wheel, making fire, and production of electricity, you can safely make and manufacture of glass.A unique combination of chemical and physical properties make them in the unique material, without which it is impossible to imagine human life.Glass - is one of the most important material which is used in construction.Generators of its components - a quartz sand, limestone and dolomite, soda and a small amount of other substances.
In 1959 was invented by a high pressure pump, which at times facilitated the work of glass blowers, and already in 1971, Englishman William Pilingtonu able to automate the manufacture of glass.This was a breakthrough in this field.Later, it turned out that the addition of the different components, the material changes its properties (e.g., density of glass is significantly increased, and therefore, it becomes more resistant to mechanical stress).A few years manufacturers figured that reheating and very rapid cooling greatly increases its strength.If all the time and temperature characteristics is easy to achieve increase in the mechanical properties of as much as four times.
The most important properties of this material is glass density, hardness, strength, heat resistance, thermal conductivity, and the fragility of the optical properties.The density is the ratio of body weight to its fullest extent.It is almost completely dependent on the chemical composition.Substantially this figure depends on the temperature.Most minimum value observed in silica glass, and the density of the glass comprising the oxides of tantalum, lead, bismuth, in contrast, is a maximum.
many years, the manufacturing process of this unique material could not be improved.In the production of glass it took a lot of time and effort.Fundamental changes have occurred in 1959 when Alastair Pilkington was published a new method called float process.It was very similar to the previous ones, but the crucial difference was the passage of the molten material during drawing through a bath of liquid tin.Glass acquired a perfectly flat surface and uniform thickness.The method has proved itself so well that is used today.
most important role in the production of plays hardening.It is such a process in which the glass becomes more secure, especially when broken.Fragments not hurt the person that is the main reason to use just such a product in the manufacture of furniture, walls, doors.Another treatment method is to bend the glass.Bent glass - a very naughty stuff, so this production meets a little less.
finished products, including tempered samples, easy to surface treatment.Sandblasting glasses - one of the most common types.The shock wave is sent to the sand in a certain way so as to clear the tracks on the glass, intended by the designer.Intricate patterns and matting effect give compelling and individuality of each glass.
Painting, too, often used in the production.Such treatment of glass found in the decoration of the walls and in the manufacture of countertops.Inexhaustible many ways allows every day to make this wonderful stuff like household items, and wonderful masterpieces.
the years varieties of glass has become a lot more, allowing its use in many fields of human activity.The main thing to remember that no matter how hard the producers to protect people during the operation, should be careful with this delicious, but still fragile material.The density of the glass and its resistance to damage has its reasonable limits!
