A Table painted in 1686 with spots of colors on paper was investigated. It appears that the Table is composed of pure pigments, and their mixtures in a 1:1 proportion. However, there were some problems when analyzing the pure compounds and the mixtures, due to the interaction of some pigments, as degradation had occurred. Possible explanations of the nature of the compound are analyzed and discussed. Copyright © 2006 John Wiley & Sons, Ltd.
