The subject of the communique is a comparison of two methods of conservation employed in the Workshop of the Conservation of Engravings and Old Books (attached to the State Enterprise for Monuments Protection) to reconstruct works of art which were in a very bad condition. One of the works is the print „The Map of the Sejneńska Diocese” by B. Gratowski, the property of the Museum of Revolutionary Movement at Białystok; the other — a wood Chiaroscuro engraving by A. Andreani „Christ before Pilat” found in the National Museum in Wroclaw. Despite added strengthenings in form of cloth and paper plying-ups, the paper of the objects displayed a marked decomposition of the fibre due to its excessive brittleness and poor adhesion to the plying-up as a result of a destructive action of microorganisms. In order to have the possibility to carry out conservation treatment on the destructed paper and also to succeed in its transfer onto a new plying-up, two variants of a protective face sizing were applied. In one case a traditional method and starch pastes were used to protect the facing and the plying-up; in the other case acetyl cellulose was used instead of a starch paste. The use of the same glue made it necessary to apply water solutions of alcohols to remove yellow discolorations. When treating with acetyl cellulose it was necessary to deacidify several times. Contrasting flues facilitated conservation procedure to a large extent. Conservation processes employed made it possible to select a less labour-consuming but equally effective method for the conservation of works of art which have a decayed groundwork.
