Válogatás az utóbbi évek magyar papír- és könyvrestaurálási munkáiból - Összefoglalók
supported with measurements, water completely surrounded the leaves immer- ged in water and thus the removal of the deteriorating agents was easier. In our case, the watery solution touched the paper floating on the surface on only one side, while the water could quickly be saturated with the dissolved acidic decomposition products around the paper. The yellowish colour that was replaced during the treatment showed that probably a significant percent of impurities and decomposition products had left the paper. The pH measurements suppported this supposition. The object was mounted with Japanese paper and wheat starch. The Japanese paper support was composed of several parts. It was stretched on a polyethylene sheet and laid on the synthetic pavement of the large room. The sheets of the fragile object were laid on a bonded polyester net, which served as a subsidiary material. Starch was spread on the surfaces of the sheets and another polyester net was placed on top. Thus the sheets could exactly be fit together with moving the three layers together. The missing parts were replaced with coloured acid-free paper glued with methyl-cellulose. In the last phase, the missing areas of the painted surface had to be replaced with watercolour. The object was restored within the frames of object conservator training conducted in the co-operation of the Hungarian University of Fine Arts and the Hungarian National Museum in 1998. Ildikó Beöthyné Kozocsa was the supervisor of the diploma work. Conservation of Sándor Runay’s funeral coat-of-arms from the 18th century Petra Serényi The funeral coat-of-arms of Sándor Rudnay archbishop of Esztergom is preserved in the collection of the National Archives of Hungary. The raw material is machine-made mould-made paper, on which the text was printed with relief printing and the coat-of-arms was painted. The upper and lower edges of the 965 mm long and 66 mm broad leaf were attached to cylindrical wooden rods. The object was very dusty and dirty, it was torn along both edges and along the rod at the bottom and it was incomplete at a few places. The paper became slightly brownish and the raw material weakened. Most of the pigments on the coat-of-arms became crumbly and peeled. To improve the condition of the object and to reconstruct its aesthetic appearance, the restorer found it necessary to carry out the wet treatment of the water- sensitive pigments without using the frequently applied synthetic fixing agents and to consolidate the peeling pigments with a material similar to the original binding matter. Information gained from the analyses of the technology and the materials helped to choose the appropriate methods and materials. A binding matter based on albumin was found during the analysis of the paint layers. The dissolution test showed that most of the pigments were not sensitive to slight moistening, while they reacted to stronger moistening. The water stain observed on the coat-of-arms necessitated the wet cleaning of the object, which had to be preceded by the fixing of the colours to the paper. Before conservation, the advantages and disadvantages of the fixing materials ge258
