Photoaging experiments on chrome yellow-based oil paint mock-ups

Description

Series of oil paint mock-ups exposed to UV-filtered light and monitored by using UV-Vis-NIR diffuse reflectance spectroscopy at different aging steps. 

Samples/file names description

a) Pure pigments

• Sulfate-rich chrome yellow (folder name; CrY0.8-pure)
• Sulfate-free chrome yellow  (folder name: CrY0-pure)
• emerald green  (folder name: emerald green-pure)
• vermilion (folder name: vermilion-pure)
• red lead (folder name: red lead-pure)
• lead white (folder name: lead white-pure)
• zinc white  (folder name: zinc white-pure)

b) Chrome yellow paints with admixed pigments in different weight ratio

• CrY0.8 : emerald green = 9:1 (folder name: CrY0.8-emerald green)
