Our research focuses on how historical pigments were made and why some of them fade while others remain stable for centuries. We recreate historical pigments using documented recipes and study how light, air, and environment affect their stability. A major focus of our work is Iris Green, a medieval pigment that behaves unpredictably—sometimes remaining stable and other times fading dramatically. By studying these pigments in the lab, we aim to better understand their chemistry and help improve conservation strategies, while training students in interdisciplinary research that connects chemistry, art, and history.
