Last weekend, a few hundred people had a look behind the curtain on the nearly-finished restoration of the Great Hall. (The scaffolds are down!) There was much discussion about the dalle de verre panels and the care that has gone into their repair.
In spring of 1965, The Stained Glass Quarterly published a feature about how the panels were created. Through the cooperation of Richard Gross at the Stained Glass Association of America, we are able to post that article and its accompanying photos here. Thank you, Richard.
The dalles are faceted and arranged by hand on the panels.
