Summary: A curator and paper conservator at the Naitonal Gallery of Art discuss Michael Heizer's Scrap Metal Drypoint#6 andits major treatment for the exhibition The Serial Impulse at the Gemini G.E.L. The treatment goal for Scrap Metal #6 was to improve its appearance by removing disfiguring stains on the paper support. Discoloration was reduced first overall in a bath, then selectively with weak bleaching solutions applied by brush.
