Developed by Associated Crafts® & Willet Hauser®, Sculptured Gold was created in the 1950s as a solution for evening masses. When there is no light shining through the stained-glass windows at night the sculptured gold technique was made to create brightness within churches and cathedrals. Each stained-glass window is covered in sheet lead that is then overlaid with 23-karat gold leaf. During the daytime the gold shimmers from the light with the colors or the stained glass shining through, but at night time the gold becomes the light within the church.
