Havasi Dóra: Egy bőrcserző céh 19. századi vaslemezre festett szállásjelvényének restaurálása
Havasi Dóra Z. • Egy bőrcserző céh 19. századi vaslemezre festett szállásjelvényének restaurálása Conservation of a 19th century lodging badge of a tanning guild painted on an iron plaque Dóra Havasi The 19th century lodging badge of red tanners was painted on both sides. To date it is in the possession of the Modern Local History Collection of the Kiscelli Museum. The way how it got to the museum and where it had originally been used are not known. The plaque base is iron. On side “A”, two inwards turning lions hold the tools that symbolise the tanners’ guild and a five-branched crown is placed in the centre over their heads. The lions, the crown and the metal rings that fix the handles of the tools were prepared from gold leaves. At the bottom, the German inscription „Die Rothgerber Herberg” can be seen in Gothic letters, while in the upper two corners the date 1835 can be read. On side “B”of the badge, a scene of offering a lodging can be seen, in which the host standa in the door and welcomes the person who asks for lodging. The console painted on the wall of the hostel and the tablet hanging from it, in which two facing lions can be seen, probably depicts the conserved object of art. The iron plaque of the lodging badge was slightly deformed. The edges were bent and injured at a few places, and two areas were missing from the acanthus leaf ornament. Formerly, the surface of the object had been covered with a waxy protective layer, which became brown and matt. The binding matter of the pigments aged, the paint layers cracked and peeled off at several places so that the illustrations were difficult to interpret. A corrosion layer covered the open metal surfaces. Microscopic comparative analyses were made of thin section samples taken from various places of the badge, which supported that the open-work frame of the plaque had been gilded on both sides and the scenes were several times repaired and repainted. First the corroded metal surfaces, on which there were no pigments and coating, were cleaned with glass pencil and manual dry-phase ultrasonic depurator, and then the brown, aged, waxy conserving layer was removed with acetone. The missing elements of the ornament of the frame were replaced with iron plaques of adequate shapes made by the same technique as the original one, which were fixed to the object with brazing. The iron surfaces were passivated with Ferropassit S50. Next, Trinát anticorrosion primer was applied on the surfaces where the paint layer was missing, which served as a conserving material as well as the first priming layer. The level differences caused by the missing paint layers were levelled with Trinát putty, which was retouched with oil paint of Louvre make. After retouching, 10 % solution of Paraloid B67 in white spirit was applied on both sides of the badge, which created tint differences in the retouching but it could be corrected. On side “A”, the retouching of the injuries of the gilded motives was made with Goldfinger gilding pigment. Matt varnish of Schminke make was applied on the surface as a final protective layer. 183
