Artists' Pigments
註釋An encyclopaedic reference developed by the National Gallery of Art, Washington, it combines two aspects of the study of pigments - the history of individual pigments and dyes and scientific methods for identifying and characterizing artists' colourants - rarely brought together in one publication. Each pigment is examined individually with extensive illustration. In addition to the history of each pigment's use, manufacture, and nomenclature, matters of concern to the practicing artist are explored, such as colour, permanence, compatibility, and handling qualities. Composition is analysed, particularly chemical and physical variations that may arise due to differences in source, methods of preparation, adulterants, and impurities. Conservation scientists will find a compendium of analytic techniques that are used to characterize and identify the pigment.
