When I was teaching at the Windward School in Santa Monica, California, I created a method of stuffing hollow water-based clay with newspaper to build oversized sculptures. This allowed me to use less clay and not have to hollow out the wet clay when the sculpture was complete. It proved so successful that I built many clay pieces in this method. 

The newspaper burns out when the clay is fired, leaving a hollow center in the sculpture. This creates a lighter weight and prevents the clay from exploding in the kiln. 

The Ringmaster was made using that technique.
