The styrene foam sculptures are hand carved by Paolo Soleri. Each wooden dowel forms a sprue [channel] in the sand through which the hot, molten aluminum is poured into the carved pieces of styrene foam. Thin dowels will form ventilation shafts. [Photo & text: Ayano Atsumi]

Styrene foam vaporizes when touched by hot aluminum. The smaller holes ventilate the gas from the burnt foam and provide escape for excess aluminum. [Photo & text: Ayano Atsumi]
