Determining the presence of photocatalytic titanium white pigments via embedded paint sample staining: A proof of principle

Twentieth century paints often contain titanium dioxide and zinc oxide based white pigments that can range from photostable to highly photocatalytic. Photocatalytic pigments can cause the degradation of paint upon UV exposure, whereas photostable pigments may be benign or can protect paintings from degradation. Hence, knowing whether or not a...

Investigating the effect of artists’ paint formulation on degradation rates of TiO₂‑based oil paints

This study reports on the effect of artists’ paint formulation on degradation rates of TiO2-based oil paints. Titanium white oil paint exists in a multitude of different recipes, and the effect of the formulation on photocatalytic binder<br/>degradation kinetics is unknown. These formulations contain, among others, one or both titanium dioxide...
