Identifying lead compounds and why they darken in white highlights in master drawings: provenance, production, trade, application and degradation.

Project: Consultancy

Project Details

Description

The aim of the project is to advance preventive conservation of drawings (as well as other objects such as photographs) with intact white highlights by using a multi-analytical approach for identifying the physicochemical properties of lead white (e.g., particle size, chemical composition and presence of impurities) and the storage conditions (e.g., relative humidity and concentrations of airborne pollutants) that make the pigment more prone to darken.
