heritage Review A Review on Historical Earth Pigments Used in India’s Wall Paintings Anjali Sharma 1 and Manager Rajdeo Singh 2,* 1 Department of Conservation, National Museum Institute, Janpath, New Delhi 110011, India; [email protected] 2 National Research Laboratory for the Conservation of Cultural Property, Aliganj, Lucknow 226024, India * Correspondence: [email protected] Abstract: Iron-containing earth minerals of various hues were the earliest pigments of the prehistoric artists who dwelled in caves. Being a prominent part of human expression through art, nature- derived pigments have been used in continuum through ages until now. Studies reveal that the primitive artist stored or used his pigments as color cakes made out of skin or reeds. Although records to help understand the technical details of Indian painting in the early periodare scanty, there is a certain amount of material from which some idea may be gained regarding the methods used by the artists to obtain their results. Considering Indian wall paintings, the most widely used earth pigments include red, yellow, and green ochres, making it fairly easy for the modern era scientific conservators and researchers to study them. The present knowledge on material sources given in the literature is limited and deficient as of now, hence the present work attempts to elucidate the range of earth pigments encountered in Indian wall paintings and the scientific studies and characterization by analytical techniques that form the knowledge background on the topic. Studies leadingto well-founded knowledge on pigments can contribute towards the safeguarding of Indian cultural heritage as well as spread awareness among conservators, restorers, and scholars.
