A FRESH FACE FOR SAMUEL GOMPERS: METHYL CELLULOSE POULTICE CLEANING
Lisa A. Goldberg
ABSTRACT—A marble bust of Samuel Gompers was evenly cleaned of surface grime and dirt, using a modified methyl cellulose poultice. The rheology, adhesion and film-forming properties of the poultice medium were modified by adding propylene glycol and fumed silica to a product with a lower degree of substitution than is more commonly used in conservation. The poultice film was peeled away after it had dried.
