Sherman Memorial Restoration
[08-12-2013 Conservation Solutions has been engaged to collaborate with the Conservancy to clean and conserve the bronze in preparation for regilding and toning the sculpture. Work began in July, 2013 and is slated to be completed in the fall. CSI performed UHP water jetting of the bronze surfaces after removal of the failed previous gilding had been complete. All surfaces were cleaned using specialized jetting nozzles under tight limits and controls to remove soluble salts that remained on the interior and exterior of the bronze. Tests showed that the technique was effective at reducing salts to a level below the international recognized standards for high performance coating systems without resulting in any damage to the bronze itself. Conservators are also consulting with the client on the toning of the gold to ensure that Saint Gaudens' wishes for the proper appearance are finally met.
