The windows that we made for Shiloh Baptist Church in Kingston, Tennessee were Faceted Glass or Dalle de Vere windows.  The glass dalles which are approximate 8 inches by 12 inches are 1 inch thick.  The dalles are cut and laid on a bed of sand.  Then an epoxy resin is poured between the dalles which results in windows that are brilliant and extremely durable.

 Faceted glass windows can “withstand temperatures of +130 degrees Fahrenheit on the exterior surface and a simultaneous of +70 degrees Fahrenheit interior surface and allow for humidity changes of 6% to 100%.  In addition, cast panels must be water resistant on tests of 25 lbs. per square foot static air pressure while 2 ½ gallons of water pass over the surface of the panel for one hour.”  SGAA Source Book 2005
