Hesse’s interest in latex as a medium for sculptural forms had to do with immediacy. Art critic John Keats stated: "immediacy may be one of the prime reasons Hesse was attracted to latex". Hesse’s first two works using latex, "Schema" and "Sequel" (1967–68), use latex in a way never imagined by the manufacturer. In her artwork "Untitled (Rope Piece)", Hesse employed industrial latex and once it was hardened, she hung it on the wall and ceiling using wire."Industrial latex was meant for casting. Hesse handled it like house paint, brushing layer upon layer to build up a surface that was smooth yet irregular, ragged at the edges like deckled paper."
