elkerülése érdekében kombinált rovar- és gombavédő-szerrel, Biokomplex Koncentrá- tum 10%-os oldatával, 150ml/m2 mennyiségben felhordva (kapható: Anticimex - Protect Kft., Pomáz) kezeltük a fafelületet. CONSERVATION OF ARCHAEOLOGICAL WOODEN OBJECTS In situ consolidation in Százhalombatta András Morgós Ágnes Holport archaeologist unearthed the Iron Age tumulus no. 115 at Százhalombatta between 1990 and 1996. This tumulus is the southernmost and one of the largest burial mounds in the tumulus cemetery at Érd-Batta. As the excavations proceeded, timber remains of a construction became visible. The tumulus contained a burial chamber built from oak planks and covered with planks and a corridor leading up to the chamber. The burial mound was built from about 5,5 m long oak trunks measuring 20-25 cm in diameter. The dismantling and individual lifting of the timbers strongly deteriorated by fungi was practically impossible because of the condition of the wood. The trunks suffering from red decay had barely any mechanical stability, the wood could easily be crumbled between the fingers. Smaller and larger fissures could be observed on the surfaces of the wooden finds, the layers detached in laminae. So the find had to be conserved in situ. The majority of the timbers were consolidated in several steps. First the surface was consolidated with low concentration epoxy synthetic resin solution (Araldit /Ciba & Geigy Co./ BY 158 type epoxy synthetic resin was used with HY 2996 Hardener and xylene as solvent). The solution was poured or brushed on the surface. The treatment was repeated several times after the applied solution had been absorbed as long as the wood surface got saturated with the consolidating liquid. The concentration of the resin was gradually increased from the initial 10 % to 30 % during the treatment. The above described treatment was repeated three times after the partial evaporation of the solvent and the hardening of the resin. After each day of treatment the synthetic resin solution was washed into the wood with a solvent so that the wood surface would not become shiny from the synthetic resin.Following the above treatments, the deeper layer of the timbers were impregnated with injection technique, when the synthetic resin used for the surface consolidation was applied. The concentration of the impregnation solution was gradually increased, just like in the case of the surface treatment. After the surface and deeper layers had been consolidated, the detached layers, fissures, worm holes and smaller holes were fixed with Paraloid B72 (Rohm & Haas C.) acrylic synthetic resin diluted in 10-20% xylene. To evade future biological decay, the surface was treated with a combined insecticide and fungicide 10% solution of Biokomplex Koncentrátum applied in a quantity of 150 ml/m2 (it can be obtained at Anticimex- Protect Kft., Pomáz). AZ ELREJTETT QUADRIPUS A POLGÁRDI EZÜSTLELET ÚJRAÉRTELMEZÉSE T Bruder Katalin, Mráv Zsolt, Veres Kálmán A polgárdi ezüstlelet jelentőségéből előkerülése óta semmit sem vesztett, hiszen a Római Birodalom területén rajta kívül nem sok hasonló tárgyat ismerünk. A lelet a maga nemében mindmáig egyedülálló, fontosságát fokozza az a feltételezett kapcsolat, amely a Seuso-kincshez köti. A cikk tartalmazza a tárgy igen alapos technikai és művészi 171
