Achrome (1960) by Piero Manzoni An unpainted monochrome canvas: Research and treatment

The Stedelijk Museum Amsterdam (SMA) collection contains three Achromes by the Italian Zero artist, Piero Manzoni (1933-1963). Manzoni’s Achromes (meaning ‘colourless’) are monochrome and mostly white. One of these Achromes, (1960), has visually disturbing stains, discolouration and tidelines, for which reasons it has not been displayed for many years. The Achromes constitute a considerable and important part of Manzoni’s multifaceted oeuvre.

The work has been treated four times in the SMA since 1970. Then, it was noticed that tide lines had formed around the local treatments. This case study provided the opportunity to identify problems than can occur in the treatment of monochrome unpainted canvasses. Various treatment methods were discussed and solutions formulated, before the treatment was conducted. The visual restoration of the Achrome concept while preserving the physical characteristics was essential for being able to show Manzoni’s intention.
