| Abstract: | Conclusions. ˙ EDS results alone (semiquantitative) do not permit unambiguous distinction among the 30 modern papers "in this sample set. ˙ Si and Ca were the only elements (of atomic weight > 11) invariably found by EDS. ˙ Elements other than Si and Ca frequently found in this sample set were S (26); Cl (25); Mg (22); Al (20); P (20); and K (17). ˙ Other elements found in this sample set were Fe (3); Na (3); and Ti (2). ˙ Seven examples had an ash content of about 1% or less. ˙ Twelve examples had an ash content >2%. ˙ Eleven examples had an ash content between 1 and 2%. ˙ Two examples had an ash content of > 10%. ˙ Three papers that contained chlorine were subjected to deionized water rinses and sodium borohydride treatment. They showed no measurable loss of chlorine content, suggesting that the chlorine in these samples was cova-lently bound. Summaries. A group of 30 modern Japanese papers are tabulated according to methods of manufacture. These papers have been examined using energy-dispersive X-ray spectrometry and grouped according to categories derived from elemental analysis, ash content and aspects of the manufacturing processes that suggest the, characterization of the papers. The papers chosen for examination are often found in works of art or are used in paper conservation laboratories. |
