Today’s Science Times features an interesting article on the science behind the increasingly boundary-pushing uses of glass in building construction, using the Sears Tower Ledge (above) as a stepping-off point.
There’s also a slideshow that highlights some other great achievements in glass construction, including those spiral staircases at your local Apple store.
For better or for worse, many designers who work with glass are trying to realize a future where structures are “unmarked by metal or other materials.”
Take, for example, this glass dome constructed with glass and a glass-to-glass adhesive:
Although the article doesn’t note this, many of the coatings applied to glass to give it steel-like strength also render it un-recyclable.
