Exploring the Use of Multispectral Imaging in Ceramic Pigment Analysis
Author(s): C. L. Kieffer
Multispectral imaging cameras are frequently used in art conservation for identifying pigments as well as monitoring change in pigments over time. Multispectral cameras take multiple images at 370nm 448nm, 476nm, 499nm, 519nm, 598nm, 636nm, 700nm, 735nm, 780nm, 870, and 940nm wavelengths with UV bandpass, visible bandpass, and long pass filters to increase the range of captured information to include UV reflectance and florescence emission images. This poster explores the ability to utilize this non-destructive technique to analyze variability of pigment recipes within ceramic types and between types. Mineral and organic black pigments from five Black-on-white ceramic types (Jemez, Cortex, Chuska, Red Mesa, and Abiquiu) from the American Southwest were used for comparative purposes. Pigment and reflectance values acquired from images via Image J software were compared both within types and between types with one-way ANOVA analysis. Results show varying levels of significant statistical difference between types and minimal difference within types.
