Gio Pomodoro Marble Sculpture Conservation - Kykuit, The Rockefeller Estate

Site
Kykuit, The Rockefeller Estate, Tarrytown, New York

Included in the Nelson Rockefeller collection of 20th century sculptures installed at Kykuit, The Rockefeller estate in Tarrytown, New York, a National Historic Landmark and a National Trust for Historic Perservation site, is a marble work by Gio Pomodoro. It consists of a single block of fine statuary grade Carrara marble carved overall with undulating biomorphic forms. It has suffered from deterioration from hyperthesis and biogrowth within the network cracking that had formed. A 1970’s treatment had complicated the conditions by developing a conversion crust on the face of the marble, which had become detached from the underlying stone and had encouraged further biocolonization. CSI carefully cleaned the soiling and biogrowth using a sequence of biocides, poutices, detergents and steam. A lead sheet cap was attached to the top of the form and shaped to match the complex profiles. Work was completed on time and under budget in 2012.
