=09 I was part of the 1991 Stonybrook University Terry-Mulford Field Project = in Orient Point, Long Island, New York. We labeled thousands of = artifacts using laser printed catalog numbers printed on acid-free paper = and laquer. It was by far the most efficient labeling technique I have = ever seen. For each artifact, we cut out a small square with a = pre-printed catalog number on it, with an exacto-knife, placed it on = the artifact, and then applied a coat of laquer over it.=20 As far as the stability of this technique is concerned, I have not heard = anything. At the National Park Service, there are federally approved = standards to follow for the handeling, labeling and curation of = artifacts. As far as I know, the only approved method for artifact = labeling is the old pen, ink and laquer (approved brands, of course). = Perhaps someone should conduct a study for the stability of the = pre-printed labels or paper and laquer methods. Does anyone know about = any? Margo Schwadron NPS-Southeast Archeological Center [log in to unmask]
