Other research teams have dealt with a wide range of artworks, particularly those made with organic materials [119,[184][185][186] (5%), with a special focus on wood [61,70,78,120,[187][188][189][190][191], leather or parchment [115,[192][193][194][195], and textiles [196][197][198][199][200][201]. Of all the tested EOs, the most common is certainly thyme, for which applications on all types of materials except photographs have been reported (Table S2).…”
