Glass production and its history trace back to the earliest times. It is known that in Egypt and in Mesopotamia people were making glass more than 6000 years ago. Discovered archeological excavations of decorative dishware, women’s embellishments certify of a booming glass and glassware production.
Usual plate glass or float is a basic material which after various types of processing turns into a final product which is always present in our daily life.
In modern world glass is a complete building material. The main consumer of glass today is a building industry.
Today light-transmission constructions play an important role both in exterior and interior of buildings. They are often used in construction of shop windows, porches, winter gardens, wind lobbies and entrance halls, for guard of staircases, balconies, terraces, lifts, parapets with the aim of prevention of falls from height, picture windows, and atriums. It would be impossible to create all this architectural magnificence without the use of the most fragile building material – glass. A wide variety of glass is used with architectural and designer aims: armored, various convex and concave glass flats, triplexes, stained-glass windows and glass packets.
Irrespective whether it is a usual window, stained-glass window or a decorative unit of furniture, for example, modern glass tabletops or fire screens our specialist strongly recommend to use only heat-strengthened glass for these articles. It is more resistant to damages and temperature differences and in case of mechanical breakdown it is smashed into safe pieces with blunt edges and not into large and sharp ones. Such glass withstands temperature up to 300 º.
Three in one
Today the builders widely use triplex or laminated glass for creation of extra-strong light-transmission constructions. It consists of several layers, as a rule of 3 ones, which are fastened with special polymer. Triplex is known as anti-vandal glass and there are reasons for that: it doesn’t break up into pieces thanks to a special membrane which fixes fragments of broken glass. Besides, this multilayer glass has noise-insulating properties. That’s why it is widely used in wall (including operable walls), floor and ceiling constructions.
Triplex is of great significance for interior designers: it can be absolutely transparent, tinted, colored, rippled, and patterned (in this case decorative inner linen is used).
Energy-saving (heat-saving) and the so-called selective glasses (solar-protective, tinted) are of special importance for dwelling-houses. The first one conserves heat in winter and coolness in summer while the latter protects against sun and ultra-violet rays. These properties the glass obtains due to a thin coat of metals. Thanks to their conductivity the material selectively admits or reflects radiation in particular wave ranges. For example, heat emissions from building to the outside go into the so-called distant IK-range while maximum of sun radiation is concentrated in a near IK-range. Accordingly, heat-saving glass has a high reflection index in a distant range conserving all heat inside the room whereas glass with a high reflection index in a near range protects from bright sun.
Electrically heated glass is rather an interesting and new product. Its main functions are protection against ice coating and providing of additional heating of rooms for establishment of a comfortable microclimate. In Europe such glasses are widespread but on our market they remain in future perspective, although the effectiveness of its applying is already seen in regions. Besides it is used in commercial and suburban building (shop windows, translucent roofs, winter gardens, French windows) and in machine-building industry (glazing cars, trains, and river vessels).
You can make the glass heat in the following ways: put a plug into a socket, set a temperature of heating, view indexes of temperature outside or connect a glass packet to an intelligent control system “A comfortable House”. But it is necessary to consider that the cost of electrical facility can many times exceed the cost of heated glass.
Frameless balcony glazing is also popular today. There are no frames between glass panels and each glass panel can be opened fully and slide to the left or right side of the balcony. The benefits of the frameless balcony glazing system are convenience and coziness of the balcony. You can freely view the surrounding sights. Glass doors and glass connecting walls are at the peak of fashion today. They visually extend the room being a noble and valuable material in interior design. Combining of tinted, transparent and patterned glass in one article is very advantageous. Sliding glass doors and transparent mobile walls are especially fashionable in interior design. In mobile constructions only tempered glass is used. Thanks to a special fixing system and rail mechanism it slides gently and noiselessly. Interior items of glass can be variously decorated: frosted, tinted, and painted with special glass stain. Any pattern may be applied to a glass flat due to such hi tech methods as photographic printing and laser marking.
New facets of glass packaging
The history of glass packaging goes back more than 3500 years. However new and new design variants, methods of casting and decoration of glass cans and bottles appear every day. Relief forms of packing, protruding logos and patterns applied with the help of screen printing and dried by ultraviolet, acid-etching and colored membrane are only a few examples of the last advanced technologies. Applying of these technologies makes any product packed in a glass packaging look impressive. It is undoubted that a glass packaging experiences a rebirth today. New technologies allow creating of containers which endure not only high-speed packing but also attract customer’s attention. One of the advantageous factors of glass packaging is a relative cheapness of glass bottles and cans (aluminum beer can costs 1.5-2 times more than a usual bottle), environmental friendliness and impermeability. Conservatism of some buyers who prefer a traditional glass packaging is also a significant factor.
