The works in the Art Museum of Estonia’s sculpture collections are conserved by the sculpture conservators Isabel Aaso-Zahradnikova and Aleš Zahradnik, as well as Hedi Kard, the conservator of polychrome wood. Since the museum has mono- and polychrome sculptures made of very different materials, the conservators must be thoroughly familiar with the physical and chemical properties of the materials being conserved and the damage they have suffered. Research is an important part of conservation work, in the course of which the historical traces of the sculpture technique are ascertained and documented. The conservators’ assignment is to halt or inhibit ageing in order to preserve the originality of sculptures. Besides practical conservation, the conservators also inspect the condition of sculptures during their storage and display.
