Glass, high-tech building materials

With its thin sticky properties, can be bent and discolored, the current smart glasses have caused people to change stereotypes about glass.

From ancient times, it is said that under ancient Rome a craftsman invented unbreakable glass and offered the emperor Tiberius a urn. He threw the jar to the ground to prove the ingredient could not be broken. But Emperor Tiberius was suddenly stunned for fear that this new material would render all of his treasures worthless. He ordered the inventor to be terminated to avoid consequences. Also from that time, the reputation of glass was scratched: glass was considered a fragile material, difficult to shape and vividly colored.

But today these statements are no longer relevant. Thanks to the thin and ultra-durable glass panels it is possible to create touch screens that even generate electricity and control light through the display’s High-Tech windows interactively. And it is not long before the malleable glass will appear on the market. The time has come to dismiss most of the prejudice against this ancient building material.

The first stereotype: “Glass is very fragile”

Steve Jobs, the boss of Apple insisted on the surface of iPhones and iPads must be made of glass at all costs. Because according to him, the glass is not only more beautiful but also does not worry about scratches and blurring compared to transparent synthetic resin materials. Jobs asked US firm Corning to make special glass that is solid and two to three times more scratch resistant for tablets and laptops. This type of glass appeared on the market under the trade name Gorilla glass for iPad and has become famous all over the world. Now Corning supplies more than 30 manufacturers of Smartphones, Netbooks, Tablets, and has a turnover of $ 6.6 billion in 2010. In the future, glass will be even thinner and harder, even thin. “Just like a hair,” predicts Peter Bocko, chief technology officer at Corning. The thinner the glass display, the sharper the image and easier to operate.

Facing the above trend, the German glass maker Schott has also introduced glass that is highly durable, withstands hundreds of degrees C high temperature and is able to protect aircraft against hail.

Recently a factory of this company has mass-produced glasses with a thickness of 0.7 millimeters – only as thin as a hair, but does not falter when stepped on. This tough, unbreakable material that Schott recently introduced will be used as a coating to increase the durability of mobile and computer screens.

To make this special glass, the Schott technicians mixed the chemical Boroxide when the glass was heated and this chemical significantly increased the strength of the material. Then this ingredient was also added by me. The molten glass will be cooled by gas.

The gas will cause the surface of the hot glass to cool down and harden on the outside, but the inside remains hot. When the glass is completely cooled, the durability is many times higher than ordinary glass. According to Schott, many electronics manufacturers around the world are currently testing this new type of super glass.

Second stereotype: “Glass is always hard”

Thanks to the glass cable, for the first time, people can build a whole house or a bridge out of glass.

One of Schott’s glass screens can be manipulated into many different shapes at a temperature of 500 degrees C but can not be flexed when cooled. But only in a while, the time will come when the material can be flexed at room temperature.

The third stereotype: “Glass cannot withstand force”

Glass innovations and innovations in the telecom sector seem blurred, but in architecture it is completely different: now glass has assumed the function of concrete and steel. Most of the facade of tall buildings is using this material. According to US market research firm Freedonia, demand for flat glass used in home construction by 2014 will increase by 6%, or about 8 billion square meters per year. Seele in Bayern (Germany) made the transparent tempered glass covering the entire main station in Straßburg and produced the seafaring glass or giant glass construction components in a new way. The name is Lamination.

Fourth stereotype: “monotonous glass of color”

LED lights in a variety of colors adorn a newly built building in Linz city.

The house of facade expert Drooghman in Belgium has a rainbow-like color on the front. Sometimes the house glows green, sometimes red is the main color, each series of colors is made up of many shimmering colored glass panels. Multi-color LED illuminated from the side has been used and the color of the LED is adjusted completely automatically.

The French maker Saint-Gobain often used this building as evidence for a new trend: glass panels will become smarter. For example, by pressing a button, the windows not only will change color but may become dull
