Orpiment is known from several locations in Japan (Palache, Berman, and Frondel 1944), but better sources of orpiment and realgar are available in China (Geerts 1878), including the world's largest realgar deposit (Silbergeld and Mc Nair 1988). Sample treated three times with water at 90°C for two hours 3. = not detected Numbers preceded by "F" are accession numbers for paintings in the Freer Gallery of Art collection A hypothesis briefly pursued was that this pigment was related to sepia, the dark brown secretion in the ink sacs of certain cephalopods, which has been used as an ink and watercolor paint in the West.

The symposium was supported by the Forbes Fund, a bequest given to the Freer Gallery by John Thacher, former director of the Dum- barton Oaks Research Library and Collection. Thacher studied at Harvard University, and, under the tutelage of Edward Waldo Forbes, director at the Fogg Art Museum, came to believe in the importance of using technical study to understand works of art. Thacher left his bequest to the Freer with the intent that the Forbes Fund be used to advance the scientific study of the care, conservation, and preservation of works of art. Both minerals were important in Chinese medicine and metallurgy as early as the fourth century b.c.e. Despite some similarities in the infrared spectra, this idea was eventually dropped on the basis of results from x-ray photoelectron spectroscopy, which showed nitrogen levels consistently too low for a material of this type.

In addition to the problems of identification, there is confusion in naming. It is not clear whether it is to be found in East Asia other than on Japanese Edo- period paintings.

The color shows some variation, some examples showing a purplish tint, but the evidence at the moment seems to sup- port a basically similar origin for all with some variability that would be likely in a mixture of complex compounds.
Sackler Gallery vii Acknowledgments I would like to thank the members of the Department of Conservation and Scientific Research for all of their efforts in organizing and carrying out the symposium. In addition, the natural mineral can be sublimed to get a more uniform product (Fitz Hugh 1997), a method described in mid- nineteenth-century Japan (Takamatsu 1878). The organic brown problem remains so far unresolved, although we have nai Towed down the field of candidates.
Conservation scientists Blythe Mc Carthy and Janet Douglas and conser- vation technician La Homa Lee, who were instrumental in the successful result of this effort, deserve particular mention. Evidence from an 1 837 text suggests that dry and wet methods were learned from the Dutch (Kitano and Koezuka 20UU). At this stage, it seems difficult to do more with examples of use on paintings, given the intractability of the inaterial and the realities of sampling, although we continue to be alert to other possible inethods.

They are complex mixtures, which include glassy particles, quartz, calcite, and starch particles as well as unusual forms of malachite and basic copper chlorides. So far as is presently known, the material is not historically described. Ono no Koniachi An identification of this pigment in terms of its source or detailed chemical constitution has so far proved elusive.

Emerald green, a synthetic copper aceto-arsenite, appears here on a single nineteenth- century painting. Conse- quently, a nuinber of approaches have proved fruitless, including gas chromatography-mass spectrometry with vari- ations on pyrolytic introduction, UV-visible absorption spectroscopy, UV-visible tluorescence spectroscopy, and HPLC.
Audiovisual specialist Andy Finch ably dealt with the variety of presentation media that the speakers had and with many last-minute anangements. By PLM orpiment particles are usually coarse and of limited transparency, with a foliated, micaceous structure. One may hope for more informa- tion from the historical record or perhaps for the discovery of a bulk sample that would permit more extensive investi- gation. 7 in Artists' pigments: A Juindhooll .lolni Goelet: 67.822 164 FIVE PROTECTIVE GODDESSES ( P ANGARA KS HA ) : COLOR NOTATIONS AND PIGMENTS Figure 2.

Especially characteristic are the distinctive anomalous green to blue polarization colors (Fitz Hugh 1997), which were generally considered sufficient for identification. Conclusions and Further Progress Work on the materials of East Asian paintings continues, concentrating now on those that are technically difficult to identify and hitherto intractable.
