Glass on Pont des Arts in Paris

 

The mayor of Paris installed two glass panels along the Pont des Arts in Paris, a new attempt to try to prevent the accumulation of "love padlocks" deemed unsightly and dangerous to safety.

The assistant to the mayor of Paris Culture Bruno Julliard (PS) decided "to try laying on the glass panels of the Pont des Arts, which replace the fences," he said in a statement Friday. "Two have been installed, a third will be in a few days," he says.

Both windows were asked, one beside the other, in the middle of the bridge, said a journalist from AFP. They devoured grids alongside the hundreds of locks and wooden panels installed for several months to try to curb this proliferation.

The "love padlocks" that loving couples are set along the parapet of a bridge to seal their union before throwing the key into the river, have appeared in Paris in 2008.

A communication campaign to encourage couples of lovers to replace the locks by "selfies" to publish on the Internet was also launched this summer, without much success.

"Within months, more than 700,000 locks were hung on several Parisian bridges," recalls Hall, which "creates a lasting deterioration of heritage and a risk to the safety of visitors."

"To the only Pont des Arts, 15 mesh panels have to be removed for safety reasons. Each of these panels was nearly 500kg lock, four times the allowable limit load" is added.

A roasting pan from the bridge, collapsed in June under the weight of padlocks, resulting in the evacuation of the pedestrian bridge that spans the Seine, connecting the Institute and the Louvre.

AGC News

 

In Belgium, the glass industry corresponds to some 7,700 jobs and a million tons produced each year. And it is in Wallonia found the world's leading flat glass, AGC Glass group.

 

Gosselies is the research center of the Belgian company AGC Glass. 30 million euros have been invested in the group's research department which now houses some 250 researchers.

 

Until then, there was the simple, double or triple glazing. But soon we will find on the market an insulating glass 12mm thick. This is one of the many projects of the Belgian company. This is revolutionary, as explained Sébastien Caliaro, engineer: "It allows for very thin with a performance that is equivalent to a highly insulating wall."

 

Combining glass with new technologies

 

Behind their computers, AGC engineers think and prepare the objects of tomorrow. However, it takes between 3 and 5 years to market a new product.

 

The glass is now intelligent, thanks to nanotechnology. For example, there are car sunroofs which have a variable luminescence, which will soon equip a great brand of high-end sedans. Another example is the combination of flat glass with LED technology which sets the tone for the future of light panels, where a simple finger slipped on the glass will make an advertisement, or a statement.

 

AGC innovates, and it is in Wallonia that this happens: "We work with all the Walloon and Flemish universities obviously we will work with other universities in the world but it is clear that it is mainly in Wallonia.. Belgium that we will find our main collaborations, "explains Marc Van Den Este, the head of research and development AGC Glass Europe.

 

The glass remains a profession of the future, especially when we know that AGC Glass employs 14,500 people worldwide and is present in all fields, including those of the World Cup football.

Miroiterie Avignonaise

Depuis le double-vitrage aux cloisons à cristaux liquides, de multiples applications appelées à se développer largement dans le verre plat

Créée en 1975, la miroiterie Avignonaise a été reprise par Étienne de Chézelles il y a deux ans, avec tout son personnel, une quinzaine de salariés : des commerciaux, des façonneurs découpeurs, des poseurs. L'atelier a été équipé d'une vitrine “verrothèque” de 150 m² où sont disposés tous les verres que la miroiterie peut proposer à ses clients.

Le  verre qui répond à trois impératifs (sécurité, confort, écologie) est utilisé à l'extérieur comme à l'intérieur : double-vitrage, escaliers, dalles de sol, clôture de piscine, signalétique mais aussi paroi de douche, miroir, étagère, plan de travail de cuisine, crédence, revêtement mural, cloison, insert de cheminée, garde-corps, dessus de table, revêtement de meuble, puits de lumière… "Avant, le travail concernait surtout le bris de verre à remplacer pour des fenêtres, explique Étienne de Chézelles. Maintenant le remplacement de casse ne représente plus  que 20 % de notre activité

Fine reduced for Guardian

The Court of Justice of the European Union reduced by 30%  the fine imposed by the European Commission to the US group Guardian in 2007 for participating in a cartel in the flat glass sector.

The fine was reduced to EUR 103.6 million instead of 148 million initially. Guardian had been convicted of an agreement on prices with its French rivals Saint-Gobain, Pilkington UK and Japanese Asahi. The agreement, which lasted from early 2004 to early 2005, concerned flat glass used in the construction sector. The Court reduced the amount of the Guardian fine considering that the calculation was unfavorable because it excluded internal sales, which favors vertically integrated companies. The Court notes that excluding internal sales in the calculation reduced the relative weight of Saint-Gobain, vertically integrated company in the offense, and correspondingly increased the Guardian, which is not vertically integrated.



Histoire de la pierre, marbres et granits :

 

Les origines

 

A l’origine étaient appelées marbres toutes les pierres que l’on pouvait polir sans aucune référence à leur composition. On a donc appelé marbres, des roches qui étaient en fait des granits, des basaltes, des calcaires… qui sont considérés comme des marbres anciens par opposition aux marbres modernes qui dérivent tous du calcaire.

Le mot marbre est dérivé du terme Grec Marmaros qui signifie "pierre brillante"

Le terme granit apparait lui beaucoup plus tard au  17 ème siècle et dérive du terme Italien "granito" qui signifie grain. D’ailleurs en Anglais on parle de "granite".

Les marbres se sont formés au fond des océans par dépôt de calcaires pendant une période située entre -380 et -330 millions d’années.

Les matières en suspension dans l'eau se sont peu à peu déposées en lits les unes au-dessus des autres et ont constitué des formations géologiques appelées bancs.

L'action de différents éléments naturels (mouvements des couches, pression, action du soleil, de l'oxygène..) ont changés peu à peu les caractéristiques originelles et la couleur donnant à la pierre son aspect définitif.

Les mouvements des couches plus profondes vont soulever et faire se déplacer ces couches de marbres que l’on retrouvera le plus souvent dans des collines en faible altitude au pied des principaux massifs montagneux.

L’action de la lumière et de la chaleur va faire cristalliser ces roches et lui donner son aspect actuel.

Ces marbres, que l’on appelle marbres primaires ne contiennent jamais de fossiles car ils se sont formés à une époque où la vie n’existait pas encore sur la terre.
