State of the Art Glass Engineering

As Unbreakable as ... Glass? (www.nytimes.com, July 6, 2009) discusses developments in the manufacture and use of glass as a structural material.

Interesting supplemental material accompanying the article includes a video and graphic illustrations of the glass booths' construction, a slide show of noteworthy applications of structural glass in architecture, and a graphic explanation of the processes for thermal and chemical tempering of glass.

A link to a video clip on youtube.com, illustrating Prince Rupert's Drop, a simple and intriguing demonstration of heat strengthening of glass in action is also worth a look.
