The white of the 20th century: an explorative survey into Dutch modern art collections

White pigments were abundantly used in 20th century paintings, and relate to several degradation risks such as titanium white mediated photocatalytic binder degradation or zinc soap formation. Knowledge about the white pigments that were used is essential for risk assessments of 20th century collections. In this study, a representative set of...

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...
