  1. I have it from a very good source. My cousin who works for a major glass curtain wall company in Monteal was at my home last week and he gave me a scoop.The company is presently working on windows for the new additions at P.E.T. and apparently sometime in 2016 a new project to replace the 50 + year old windows on the main building will be launched. I am hoping that he is right. :shhh:
  2. Hot new Vdara hotel might be a little bit TOO hot Bill Pintas was vacationing in Las Vegas when he decided to stay at the swank new Vdara hotel, a curvy 57-story tower owned by MGM Resorts. He was sitting at the pool when he encountered something alarming. He recalls, "I'm sitting there in the chair and all of the sudden my hair and the top of my head are burning. I'm rubbing my head and it felt like a chemical burn. I couldn't imagine what it could be." Like an ant under a magnifying glass, he remembers running to an umbrella, but being unable to escape the hot light. He recalls, "I used to live in Miami and I've sat in the sun in Las Vegas 100 times. I know what a hot sun feels like and this was not it. My first inclination was thinking: Jesus we've destroyed the ozone layer because I am burning." Speaking with employees, he was alarmed to find out that the hotel staff was aware of the situation. He recalls, "They're kind of giggling and say: 'Yeah, we know. We call it the death ray." The "death ray" appears to be created by the glass surface of the hotel itself -- acting as a concentrating parabolic dish -- similar to those used to heat water to a boil in solar power systems. The dish concentrates light on a 10-foot by 15-foot hot zone moving across the pool. Temperatures in this area spike 20 degrees Fahrenheit -- or more. Bill Pintas saw his plastic newspaper bag literally begin to melt. The bag -- composed of polyethylene -- is designed to withstand temperatures of up to 120 to 130 degrees Fahrenheit. And the employees recall seeing plastic cups -- which have a melting point of 160 degrees Fahrenheit – actually melting. Other guests, including newspaper reviewers, have also observed the burning beam. The hotel management doesn't call it a "death ray", they prefer the more friendly distinction "solar convergence phenomenon". Gordon Absher, a spokesman for MGM Mirage says the hotel is addressing the problem, and comments, "Because of the curved, concave shape of that hotel, they sometimes get isolated pockets of high temperatures." The hotel is baffled by how to solve the problem of the "death ray", though. When initially constructing the building, they anticipated the issue and put a coating over the glass that absorbs 70 percent of the daytime sunlight. However, that was not enough to reduce its painful effects. And the ray sweeps across a wide area, making it hard to protect a specific region. Comments Mr. Absher, "This is quite literally an astronomical challenge," Absher said. "We are dealing with a moving target." The mishap in architecture isn't as glaring as some of history's most notable mistakes -- such as the 1940 Tacoma Narrows Bridge, but it is pretty extraordinary. It serves as a reminder that while many take the science and engineering of designing massive skyscrapers for granted these days, it remains a tricky business. It looks like the Vdara may have exposed the wrong guest to the death ray, though -- Mr. Pintas is a Chicago-based lawyer. http://www.dailytech.com/Hotel+Accidentally+Makes+Solar+Death+Ray+Burns+Lawyer/article19756.htm
  3. Just follow the light: Traffic lines stay brighter going in one direction A recent study by North Carolina State University has shown that the stripes dividing our nation's roadways are brighter when they are applied in the same direction that traffic is flowing. In many cases, the twin center lines dividing opposing lanes are painted at the same time, making them more visible in one direction than the other. The issue seems to center around the glass beads that are mixed in with the paint. These reflective beads are most effective when properly oriented. Using a device called – we're not making this up – a retroreflect-o-meter, the team discovered that the difference in the reflective values of painted lines put down in the proper direction was great enough that they could sometimes last an entire year longer than if they were painted in the opposite direction. These findings indicate that the transportation authorities could save quite a bit of money if they go the extra step of ensuring the lines are applied in the correct direction. Additionally, safety would be improved since the lines would be more clearly visible at night. Other more costly alternatives include adhesive tapes with glass beads already embedded in the proper direction. Who knew? http://blog.wired.com/cars/2009/03/traffic-marking.html
  4. Toronto Star, May 19, 2010. By Carol Perehudoff I don’t dare sit down in this glass-encrusted dress. If I break one of the attached silvery rectangles, not only will I damage a piece of art, the splinters would be a serious pain in the you-know-what. “You’re the first person to try it on,” says designer Jessica MacDonald as I twirl around Espace Verre, a glass arts school, studio and exhibition centre housed in a former firehouse in southwest Montreal. I’m not sure how I convinced Jessica to let me try on the dress or how it fit over my hips after the almond croissants this morning at Patisserie Kouign Amann, but it’s a great introduction to “Montreal, City of Glass,” a year-long celebration of the city’s most translucent art form with more than 100 glass-themed events. That’s reason enough to visit, but I’m also on the trail of a mystery: “The Mystery of the Disappearing Windows.” This intriguing headline on the website of Notre-Dame-de-Bon-Secours Chapel appealed to my inner Nancy Drew. It’s hard to sleuth in a glass couture outfit, however, so reluctantly — and carefully — I shed the dress and accompany my guide, Marie José, to Old Montreal, where the chapel was founded in 1655 by Canada’s first female saint, Marguerite Bourgeoys. Unfortunately the church doors are locked. “How am I going to solve the Mystery of the Disappearing Windows now?” I ask. “Do you mean the disappearing glass at Notre-Dame Basilica?” Marie José asks. “There’s a mystery there.” Either there’s an awful lot of vanishing glass in Montreal or I’m mixing up the two Notre Dames. To find out, we head down to Notre-Dame Basilica at Place d’Armes Square. Completed in 1829, this towering neo-Gothic basilica is a stained-glass showcase containing windows from three different historical eras. Like celestial skylights, three rose windows are set in the ceiling; in an unusual touch, the side windows depict historical rather than biblical themes. “But what about the mystery?” I ask, gazing up at a scene of Jacques Cartier coming upon the Iroquois village of Hochelaga (today’s Montreal). “It started with arson.” Marie José leads me to the back of the church. “In 1978 someone set fire in a confessional, causing millions in damages. During renovations, five stained glass windows were found behind a brick wall. They’d been walled up and forgotten for more than 80 years.” Two of the windows, St. Peter and St. Louis, now hang in the Basilica’s Sacred Heart Chapel. Masculine and medieval-looking, they glimmer with deep tones of blue, burgundy and gold. “Why would anyone cover them up?” I ask. Marie José offers a solution. “The windows were right behind the altar, so parishioners couldn’t see the priest during services because of the sun shining through.” Well, that’s one mystery solved. It’s not my original mystery, however, so the next morning I return to Notre-Dame-de-Bon-Secours Chapel. The current domed church dates to 1771, the foundations of the original chapel now mere stone traces deep in the church cellar. I hunt up Karine St-Louis, head of educational programming, who gives me a rare peek into the cellar’s depths. An eerie-looking room with ancient timber supports, it lay abandoned for decades, filled with dirt and debris. Then, during an archaeological dig here in 1996, two stained-glass angel fragments were found. “They were part of a much-larger window made around 1855,” Karine says. “It was either the Assumption of Mary or the Immaculate Conception.” “Who made them?” “We don’t know.” We visit one of the angels — now on permanent display in the chapel museum. Backlit, the angel glows with a luminous calm, his green wings and golden hair framing an unreadable expression. It’s hard to imagine that before Canada was even officially a country he stood watch in the chapel, then waited more than a century to re-emerge. “Who saved it, I wonder? And what happened to the rest of the window?” Karine smiles. “That’s the mystery.” “Why would anyone remove it?” This is something she can solve. “Like anything, glass goes in and out of fashion.” From stained glass angels to couture cocktail dresses, it certainly does. Evidently it can disappear and reappear, too, carrying with it fragments of history. Montreal may be the City of Glass, but it’s a city of secrets, too, making me wonder what other mysteries lie hidden behind its historical walls. http://www.thestar.com/travel/northamerica/article/811043--montreal-a-city-of-glass-and-secrets Here is a video by Ms. Carol... a little bit funny! http://www.thestar.com/videozone/811042 "In the end, I've come to the conclusion that Montreal is alot like glass. It shimmers its tiny shiny pieces that make up an incredible whole. And if you catch it in the right light, it's iluminating! "
  5. Owens-Illinois closing Toronto glass container plant, Last Updated: Tuesday, July 29, 2008 | 9:02 AM ET The Canadian Press Owens-Illinois Inc. is closing its glass container plant in Toronto effective Sept. 30, affecting 430 workers. The company said Tuesday that the closure arises from an "ongoing review of its global manufacturing footprint," and the Toronto plant's production will be shifted to other factories, including sites in Brampton, Ont., and Montreal. "This closing was driven by our global asset utilization process which identified the opportunity to shift our production to other O-I North American facilities, resulting in lower energy consumption and production costs while still meeting current and anticipated market needs," stated Scott Murchison, president of the 24,000-employee company's North America glass containers division. "The market impacts of a strong Canadian dollar, high energy prices and the recent activities of the Liquor Control Board of Ontario were contributing factors."
