Thanks so much to Jackie Urgo from the American College of Building Arts in Charleston, South Carolina for sharing the details of this great project with us.
A 3-D scan was made of the ornamental plaster in the steinway building in New York before it was demolished. Plaster is reconstructed superbly.
You may have just seen this picture, but I wanted to put the whole history on one page. Design is traced from the 3-D scan.
Print out from the 3-D scan shows the depth of this rosette.
A template is made to carve the filigree, or intricate design, into the clay model.
Clay is shaped into a circle and marked off into six slices.
