Titanium white: Friend or Foe?

Titanium white pigments can cause degradation of oil paints through photocatalytic degradation processes. On the other hand, highly photostable titanium white pigments, protecting their surroundings from degradation, also exist. Due to the limited age of paintings containing titanium white (max. 100 years) and the wide variety of different qualities of titanium white pigments that have been on the market it is very hard to predict and with that prevent photocatalytic degradation. I will present an overview of my PhD research. My aims were to characterize the extent of titanium white pigment use in the 20th century, detect early warning signs of degradation and predict degradation. My research results in a risk assessment and management strategy recommended to modern art collections.

Birgit van Driel obtained a Masters in Material Science from the École Polytechnique Fédérale de Lausanne. She just submitted her PhD, carried out under collaborative supervision by the Rijksmuseum, TU Delft, the RCE and AkzoNobel.

Technical developments in the art of painted wall-hangings

The five-year research project From Isolation to Coherence, led by dr. Margriet van Eikema Hommes, focuses on painting ensembles in Dutch interiors from the late 17th and 18th centuries and combines art-technological and art-historical research. and studies paintings’ materials and techniques, investigates the visual coherence of the ensembles and examines their sociohistorical context. The practice of decorating a room entirely with painted wall-hangings (‘geschilderde behangsels’), commissioned for a specific location in contrast to easel paintings, enjoyed great popularity in the Netherlands from the last quarter of the 17th century onwards. Formal aspects such as colour, light, composition and perspective were typically adapted to the chosen location, and the increased scale of the paintings necessitated adjustments in the artists’ painting materials and techniques. This talk presents findings on these material-technical and stylistic developments through several well-preserved ensembles that have remained in situ.

Ige Verslype is a paintings conservator at the Rijksmuseum and a PhD candidate in the project ‘From isolation to Coherence’, supervised by prof. dr. Joris Dik and dr. Margriet van Eikema Hommes (TU Delft).
