Gil, Milene; Costa, Mafalda; Valadas, Sara; Cardoso, Ana Margarida; Helvaci, Yigit Zafer; Bhattacharya, Sriradha; Candeias, AntónioThis chapter reports the analytical study carried out on Almada Negreiros’ two working palettes in the public hall of the DN Building in 1939. Both palettes were hidden behind wooden cabinets and discovered in 1991 during conservation works. The first study carried out in 2021 focused on the identification of cadmium pigments. In phase 2, the goal was to extend the research to other colour materials to ascertai...

Bhattacharya, Sriradha; Caldeira, A. Teresa; Chapoulie, Rémy; Ferrier, Catherine; Mirao, José; Lacanette, Delphine; Bassel, Léna; Salvador, CátiaMicroorganisms inhabit all possible environments including hypogean environments.

Gil, Milene; Costa, Mafalda; Cardoso, Ana; Valadas, Sara; Helvaci, Yigit; Bhattacharya, Sriradha; Moita, Patricia; Candeias, AntónioThis paper reports the first analytical approach carried out on two working palettes by Portuguese modernist master Almada Negreiros, found in 1991 behind old wood cabinets at the DN building in Lisbon. This is the only known occasion Almada left behind the color experiments done before starting to paint in the nearby walls and as such, it is a unique opportunity to analyze the materials and painting techniques...

However, over the last decades living microorganisms have been associated with structural and aesthetical damages to building st...
