When building his own house in Kings Road, Hollywood (see here and here), Schindler used Irving Gill’s tilt slab method of casting his walls on the floor slab they had already cast. They started casting in Clyde Chase’s studio, where you can see evidence of the burlap separating layer in the castings. Schindler’s studio was the last on the list, by which time they had worked out the process. In Marion Chase and Pauline Schindler’s studios you can see how they got there. Here are samples from Clyde Chase and Rudolph Schindler’s studios.
