The largest piece of curved glass in the world is installed in the Apple headquarters.
“…one of the coolest innovations of the new headquarters is its curved glass. More than 3,000 sheets of it will wrap around the entire building. All the panes were shipped from Southern Germany, where the manufacturer, Sedak, is located.” (Business Insider)

Combining other minerals with the sand, lime, and soda ash can result in different colored glass. For example, adding nickel oxide to the mix produces violet glass. (Techni-Glass)
