From 1988 to 1991 Katherine owned and operated a bronze foundry on the Olympic Peninsula, west of Seattle, where she cast her own sculptures using the ancient art of lost wax casting. In 1990, a video was produced about Katherine's bronze sculpture.
Embryo: the Art of Lost Wax Casting, shows the alchemical and poetic foundry process set to the chanting, drum and flute music of Carlos Nakai.
