_ Andrzej Dajnowski - 3 - <br /> amount of zinc, tin, and lead. The project compared metallurgical and working properties of this <br /> metal. Samples of several compositions have been cast at a local foundry. After cold working <br /> and hot working, cross-sections have been made and studied for structural differences. <br /> A paper on this topic was presented at the Conference of Conservation Students in <br /> Buffalo - 1988, and published at Art Conservation Training Programs Conference. <br /> ANALYTICAL EXAMINATION OF CHINESE LIANGZHU NEOLITHIC CERAMICS <br /> Eugene F. Farrell and Andrzej Dajnowski <br /> This paper is an attempt to understand technique of manufacture of neolithic Chinese <br /> ceramics from the Liangzhu culture (3rd-4th millennium BC). During this period various types of <br /> wares were in use. The most intriguing are those objects that have a black core and two gray <br /> layers, one exterior and other interior, with both surfaces covered with a thin black coating. <br /> The origin of the black and gray layering and methods of manufacture are questions that <br /> we were trying to answer using modern analytical techniques. This paper discussed the results <br /> of thermoluminescence analyses, quantitative electron beam microprobe analysis, <br /> x-radiography, binocular microscopy of thin sections, and XPS analyses of the samples. These <br /> analyses have led towards an understanding of the interesting group of early ceramics. <br /> The paper has been presented at American Institute for Conservation 17th Annual <br /> Meeting in the Objects Group Session (1989) <br /> THE TECHNICAL EXAMINATION OF SOME NEOLITHIC CHINESE LIANGZHU <br /> CERAMICS IN THE HARVARD UNIVERSITY ART MUSEUMS COLLECTION <br /> Andrzej Dajnowski, Eugene F. Farrell, and Pamela Vandiver <br /> The research started at Harvard University continued at the Conservation Analytical <br /> Laboratory of the Smithsonian Institution (1991) where with help and generous support of <br /> Pamela Vandiver the firing temperature was established, and additional information on the <br /> manufacturing technique was provided. <br /> A paper on this topic was presented at 1992 Materials Research Society Annual Meeting , <br /> in San Francisco, CA., and published at Materials Issues in Art and Archaeology Vol. 267.
