Entre a tradição e a modernidade: os pigmentos ao dispor dos artistas e o conhecimento sobre esses materiais em Portugal no início do século XX

In this paper some notes are presented in a dictionary format about composition of pigments applied in painting and their actual equivalence. These manuscripts were probably written in the 1920’s and their non-identified author had considerable experience in pigments’ preparation and also solid chemistry knowledge. The dictionary presents 150 entries and aims to become a useful tool for the interpretation of pigments references in documental sources from this time. Besides it allows identifying the pigments a conservator-restorer may find while performing a conservation intervention on an early 20th century painting.
