Session Basics
Session Type: Symposia Session Number: 1020
Session Title: Recovering the Original Colors of Paintings through Analytical Chemistry
Room: 263    
Session Date: 03/10/2015 - Tuesday Day of Week: Tuesday
Morning/Afternoon: Morning
Overview: Colors observed today in paintings are not always those desired by the old Masters. Many pigments aged catastrophically: fading, reactions with light, humidity or binders, etc. Modern analytical methods and new chemical concepts provide better understanding about such complex chemical phenomena which can thus be virtually “inverted” to restore original paintings colors.
Session Organizer(s): Christian A Amatore, Philippe Walter
