Willi Baumeister's Paintings Analyzed Using Non-Destructive Techniques to Reveal Material Composition
A comprehensive study has been conducted on the paintings of Willi Baumeister using non-destructive and micro-invasive analytical methods. The investigation, carried out by multiple institutions, aimed to uncover the materials and stratigraphy of Baumeister's artworks. Techniques such as stereomicroscopy, vibrational spot-analysis, and imaging methods were employed to map the distribution of materials in the paintings. The study revealed the use of various pigments, fillers, and binders, including lead white, zinc white, titanium white, and cadmium-based pigments. Additionally, organic materials like buttermilk and polyvinyl acetate were identified, suggesting their use as binders or surface coatings. The findings provide insight into Baumeister's artistic techniques and material choices between 1930 and 1955.
