The technical study of the painting Portrait of Giovanna Tornabuoni presents detailed information about the research conducted by the Conservation Department of the Thyssen-Bornemisza Museum to shed light on the creative process, techniques and materials used by Ghirlandaio.

The ensuing exhibition and publication display the results obtained in the Museum’s laboratory using X-radiography, infrared photography and microsamples, which have been crucial in identifying the working technique and the material composition, as well as the distribution of strata in the painting.
