Many of the methacrylate polymers used at the beginning of these Investigations were prepared by Stuart Raynolds. Richard A. Tauson carried out the Initial studies on the effect of temperature. The authors wish particularly to thank Dr. John Walker, Director Emeritus of the National Gallery of Art, for his great personal interest, support, and encouragement In this research. The work of the Center Is principally made possible through the generosity of the Andrew W. Mellon Foundation.

Mainly linear. If the periodic table is transformed into a spiral sculpture, it would be mainly solid. If a mobile periodic table is created, a linear, three-dimensional work of art would result. Famous artworks that resemble a mobile periodic table are the Alexander Calder mobiles. A good example is Untitled at the National Gallery of Art in Washington, D.C. Two red metal pieces represent the s elements, and six black metal pieces represent the p elements.

Last I would like to mention the interesting case of two bronze statues. One, Man with a Beard, a handsome Renaissance bronze statue was owned by the Louvre in Paris, whereas the other, Boy with a Ball, was owned by the National Gallery in Washington, D.C. (8). These two statues were remarkably similar in style, and it was suspected that at some time these may have been part of one artifact. Stylistic analysis, however, was not sufficient to make the final decision. X-ray fluorescence study of the two objects showed identical chemical composition which can happen only if they were poured from the same batch of metal. The analysis also showed that by composition the artifacts were closer to brass than to bronze. The group was reunited and is now known as St. Christopher Carrying the Christ Child with the Globe of the World. The statue illustrates the legend in which St. Christopher carried the Christ Child across a river.
