Preservation and restoration of the medieval Easter egg from archaeological site Gudovac-Gradina

U ovom su radu prikazani konzervatorsko-restauratorski radovi na ukrašenom uskršnjem jajetu, pisanici iz druge polovice 15. stoljeća. Pisanica je pronađena na arheološkom lokalitetu Gudovac–Gradina u blizini Bjelovara, u čijem je gradskom muzeju i pohranjena. Opisane su sve faze radova, od dokumentiranja postojećeg stanja, procesa čišćenja, sklapanja ulomaka, restauriranja, izrade crteža u mjerilu do dokumentiranja stanja nakon provedenih zahvata. Navedeni su materijali i metode korišteni tijekom radova i preporuke za pohranjivanje i rukovanje restauriranim predmetom. Zbog visokog stupnja oštećenja predmeta, zahvat je bio vrlo složen. Sve intervencije na predmetu izvedene su uz poštovanje njegove izvornosti i restauratorske etike, a primijenjene metode i materijali zadovoljavaju uvjet reverzibilnosti. Restaurirana pisanica rijetki je sačuvani primjer kontinuiteta tradicije narodnih običaja vezanih uz vjerski blagdan Uskrsa od srednjeg vijeka do danas.This article presents the conservation and restoration works done on the decorated Easter egg from the second half of the 15th century.
