These photos illustrate some of the materials, methods and tools used in the Earley process to fabricate precast architectural concrete of the exposed aggregate type.
These historic photographs were taken inside Earley Studio’s shops while the craftsmen were producing the precast components for the Baha’i House of Worship in Wilmette, Illinois.
Prints of these photographs are in the collection of the National Baha’i Archives of the United States. With the Archive’s permission the images are presented here for educational purposes.
