the restoration. With their help, the process of the creation of the wall paintings and the applied materials could be reconstructed. The authors describe the use of the organic red pigment found in the mural painting and publish observations on the appearance of the changed cinnabar. Restoration started with the removal of the dust and soot layer that was strongly adhered to the surface. The first step was dry cleaning, followed by a chemical treatment. The mixture of ammonium-carbonate and the disodium salt of ethylene-diamine-tetra-acetic acid (Selecton B2) was applied combined with water wash. This process was repeated as many times as it seemed necessary. We had to be careful with the colours that had lost adhesion, which could only be cleaned after a preliminary conservation. Different chemicals were used for the removal of salts when loose salt crystals or persistent scale covered the surface. The next step was the removal of former repairs and overpainting. Packing with the mixture of ammonium-carbonate and Selecton B2 proved useful to remove the overpainting, which was completed with mechanic cleaning with a lancet and a brush. In the followings, the plaster was completed and sealed. The blistered yet complete plaster surfaces and the plaster areas that had weakened at the structural cracks were fixed back with Plextol B 500 (acrylic dispersion) injected under the plaster. After cleaning and the completion and the sealing of the plaster, the entire surface was conserved with the 2.5% solution of Paraloid B 72 in nitro-diluent. Then the incisions were copied on a transparent sheet, on which the lines of the fissures were also marked. The daily seams, which reflected the chronological order of the painting of the fresco, were also found and drawn on the sheet. With the observation of the seams, the directions of the overplastering could be observed and comparing them, we could determine the order of the painting of the surfaces. The drawing made in a scale of 1:1 is suitable for the complex analysis of the wall painting, which is a singularly well preserved mural painting complex in Hungary. Closing the process, invisible retouching was applied to accomplish the aesthetic reconstruction. Restoration of the mosaics decorating the interior of the Deák mausoleum Mária Brutyó Ferenc Deák was an eminent Hungarian politician of the 19th century. His mausoleum, one of the most significant buildings of the Kerepesi cemetery in Budapest, was completed in May 1887. A rapid deterioration started in the building soon after its construction due to unsolved mechanical problems, construction problems and inappropriate building materials. The grave damage caused by World War II, aggravated this situation. The exterior and interior renovation of the building and the restoration of the mosaics were carried out in subsequent phases between 2000 and 2003. Classical architecture is characteristic of the exterior of the building: it shows the stylistic traits of the Italian renaissance. The interior can be divided into three levels, in which surfaces of marbly patterns (artificial and real marble) alternate 183
