L’évolution des réfrigérateurs

L’ancêtre du réfrigérateur moderne est sans nul doute le modèle Monitor Top de General Electric commercialisé en 1927. Pesant plus de 275 livres d’acier, cette bête en acier propulsa l’industrie de la refrigeration domestique vers ses premiers sommets. Ce modèle fut rapidement accompagné d’une extension faite de stainless steel qui permettait la congélation d’aliment. L’acier stainless permettait entre-autre d’éviter la rouille et l’usure du fuselage.

Durant les années 1950, l’industrie du réfrigérateur visa davantage la classe moyenne. Le modèle Northstar fut emblématique de son époque. Pesant plus de 350 livres, ce réfrigérateur était composé d’acier stainless. Il fut également le réfrigérateur qui amorça la tendance decorative des réfrigérateur. Les femmes au foyer pouvaient maintenant choisir la couleur de leur mobilier de cuisine. La tendance vers le recouvrement d’acier inoxidable débuta à cette époque.

Après quelques décennies, arriva les nouveaux modèles des années 1980s. Nouvelle époque, nouveau design. Capitalisant moins sur l’image de fiabilité et de fierté nationale que représentait l’acier, les nouveaux modèles des années 1980 misaient d’avantage sur l’efficacité énergétique et utilitaire. On peut voir ici un des modèles fer de lance de l’époque : un réfrigérateur de marque Fisher and Paykel.

Aujourd’hui les réfrigérateur ne sont plus uniquement des outils de cuisines, mais églament des éléments de decoration. Les modèles aux portes françaises, avec machines à glace ou même fonctionnant à l’aide d’internet ne saissent de repousser les limites de l’imagination.  De leurs humbles et frustes débuts, les réfrigérateurs ont su travers les époques poussés  par l’esprit innovateurs de leurs concepteurs.

The Stained Glass Industry Needs Copper Foil

The art of stained glass as existed since the Antiquity. One of the most famous and ancient usage of copper for artistic glass was done by the Egyptian. The glass craftsmen of Ancient Egypt use copper to give a bright and beautiful green and blue tone to the pieces.

During the 19th and 20th century that copper was added to the work pieces of religious glass art.  To obtain a dark red, crimson like effect very high concentrated copper was including in the glass staining process. This process allowed the early Christian glass stained craftsmen to perform their art in order to create the masterpieces of their time.

Nowadays, artisans, artists and craftsmen of stained glass use a different kind of copper to embellish their pieces. Copper foil tape is now applied directly to the glass, allowing artists to get more flexibility in the shape and taint of the material. Indeed, by changing the chemical composition of the alloy, the copper’s color can go from a pale grayish tone to a dark crimson red.

Why is the Statue of Liberty Green?

If you ever traveled to the astounding New York City before you most likely went to see the Statue of Liberty from very close. If not face-to-face you might have seen it on TV or stamped on a travel magazine, andvery often Hollywood movies play a scene or two, romantic or not. From far or close everyone could recognize it, the symbol of freedom and democracy in the heart of NYC.

The Statue of Liberty was a special gift from France to the USA as a representation of friendship during the Revolutionary War. It arrived in New York Harbor on June 19, 1885. The statue came in 350 pieces and was assembled once got in America. The Statue of Liberty Represents the Roman goddess of freedom, Libertas, holding a torch in one hand and a tablet with the date of the Declaration of Independence in the other.

Built in France, the statue is made of hundreds of thin copper sheets assembled on a frame of steel support. The thickness of the copper outer layer is only 3/32 of an inch – the thickness of two pennies put together. Despite how thin it is, the copper is strong. The amount of copper in the Statue of Liberty could make 30 million pennies!

The statue’s original color was dull brown, reflecting the natural color of its copper plates. However, due to a natural weathering process, oxidation, air and water reacted with the copper plates, turning it slowly to the green color you see today. Although some people thought this process meant it was rotting, the weathering of the copper created a thin layer of copper carbonate, called a patina, which actually protects the copper underneath from further corrosion.
