Will Wittig's concrete is translucent

Assistant Professor of Architecture Will Wittig
Assistant Professor of Architecture Will Wittig is taking part in something
that seems impossible. He and a group of architects are creating walls of
concrete that let light shine through. In the exhibit "Liquid Stone,"
at the National Building Museum in Washington, D.C. Wittig and other architects
demonstrate a variety of methods for creating concrete that can transmit light.
Wittig?s exhibit consists of panels of concrete that in some places are only
a tenth of a inch thick. He says that he has ideas about an all-concrete building,
part of which would consist of ordinary opaque concrete and translucent concrete.
The exhibit is on display until April 2005. Visit www.nbm.org
to see examples of Liquid Stone.
