Coil Building Technique with Nylon Fiber Clay

I just returned from a workshop presented by Adrian Arleo at the Clay Studio of Missoula. She taught us how to construct a figure, adding coils from the bottom upward. As it was difficult to guesstimate how big the cross sections of the thighs should be, mine got a way bigger than I had intended. However, the clay with a small amount of nylon fiber and lots of grog held the sculpture together. It will be finished with terra sigilata and stains and then fired in two pieces.

Being environmentally conscious, it will bother me to pollute the air with the combustion of nylon fiber, a byproduct of petroleum. I don't have enough experiences to tell definitely, but I think I can easily substitute nylon with cellulose. Regardless of which fiber we add in the clay, it should prevent cracks.
