Clay pipe sculpture display at Building Products – Mission Clay, Phoenix, Arizona. The five colorful, cartoon-like pieces in front are by Patrick Siler; the small pipe at center back is by Cameron Crawford; the large pipe with red imagery at far right is by Alan Chin. All artists used commercial underglazes and clear glaze.

When Nancy Scotto arrived at the factory, she chose to coil-build her 7 ft. tall, 2,000 lb. clay amphora shapes. The extruded clay pipe did not suit her design, leading her to seek technical ceramic assistance from Eric Struck in developing a cone 3 sculpture paper clay. The eight-month project included fabricating massive pieces for a public art installation at Foothill High School in Pleasanton, California, in conjunction with her students.

Figurative sculptor Lisa Reinertson arrived at the Mission Clay factory to explore bas-relief ideas. When she set foot in the factory, she remarked, "It was so cool to watch them extrude my pipe from the gigantic machine." The pipe was delivered to the studio by forklift, where she worked from a live model to articulate a figurative image onto the clay. One aspect of her research was to determine whether traditional hand-modeling stoneware and terracotta clays were materially compatible with the factory-extruded clay body. What she discovered was that cracking and adhesion problems occurred due to differences in clay formulation and shrinkage.
