January 2012: I recently attended my third Heaven on Earth workshop in Todos Santos, BCS with Donna Billick. This year’s project was a “community build” featuring a 12 foot Aztec Calendar made from a combination of handmade ceramic pieces, concrete and mosaics. The final results were installed outdoors in the town’s center. I continue to be amazed at how versatile concrete can be. The center piece of the calendar is a sun face about 18 inches in diameter. First we molded the face with ceramic clay. Then polyurethane was poured over the whole thing to create a mold. A plaster mother mold was also made which supports the polyurethane once it is filled with concrete. Then the face was cast in the polyurethane mold with tinted concrete.
