After completion of the process, the particles present in the precipitated and
suspended forms in the electrolyte solution were filtered and washed, respectively.
In writing about her project, Barlow mentions the
suspended forms in the Tate's collection, among them Claes Oldenburg's Giant Three-Way Plug, Scale B, 2/3, 1970; Marisa Merz's Untitled (Living Sculpture), 1966; and Rebecca Horn's Concert for Anarchy, 1990: "They were instrumental in demonstrating to me how suspended sculpture can be more ambivalent than grounded or plinthed works.
(I have often argued that this optical/conceptual hybrid was present in the early work of the New York artist, Sol LeWitt, who flatly denied it.) Yet in Soto there is a consistent trajectory as he moves from the early abstract paintings to the serial grids, then to the
suspended forms, as in "La Cocotte" (1956), a section of an incomplete open cube that would predate both Francois Morellet and again LeWitt by several years.
