Pigments in art restoration and research de fatima.muralha
Pigments are substances that provide colour through their ability to absorb and reflect light of different wavelengths.
They contain fundamental elements for the treatment of a work of art, as well as providing valuable information about the period, the style and techniques of the artists, their origin and authenticity. One of the fundamental aspects is the study of the chemical composition of pigments and how this affects their colour; or their physical properties that inform the way they interact with light.
Pigments can come from different sources and their chemical structure is important in determining their optical properties and stability.
The study of pigments is a multidisciplinary field that combines chemistry, physics and biology, as well as art history and other fields, to understand pigments and their behaviour. This study is fundamental to the appreciation, conservation and authentication of works of art.
