Old window glass making technique. Corning Museum of Glass, New York, USA.
Glass is thicker at bottom of very old window panes due to the centripetal force of a glassmaker's rotating punty iron. The fascinating Corning Museum of Glass (CMOG.org) covers the art, history and science of glass, brought to life through live glassmaking demonstrations, offered all day, every day, in Corning, New York, USA. The not-for-profit museum was founded in 1951 by Corning Glass Works (now Corning Incorporated) and has a collection of more than 45,000 glass objects, some over 3500 years old, the "world's best collection of art and historical glass."Add to Lightbox Download
