Karen Good’s high school ceramics class from the Orme School in Mayer, Arizona, visits Arcosanti on a field trip. They are here to learn silt-casting, a technique used to make many of the concrete forms on site. They, however, will apply the technique to make plaster tiles. The students pack silt (very fine deposits) from the Agua Fria River into wooden forms, and then carve and paint designs into their square of silt.

Charles Provine, Arcosanti’s public relations coordinator, helps students pour plaster over his design. The plaster will take the negative form of the carving, and harden into a finished tile.

Arcosanti often hosts student groups for silt-cast and other workshops; for more information, please contact Charles Provine.
