after it in a freezer, where they remained six months (photo 1). The leather kept iron in it, because the soil was rich in iron as we saw during the determination of the iron content( it was 3,8 at the atomic absorbtion). The iron protected the leather from the degradation. Humidity was 11-14%, and the value of pH was 3-3,5. The biological analyses led us to the conclusion that the objects had not been biologically deteriorate but the visual examination, completed with physico-chemical analyses, diagnosticated an advanced process of physico-chemicaldegradation: dehidrated, craked, stiffed, frail and scaled leather. After repeated examinations, corroborated with the results of the physico-chemical analyses, the working technology was established. At the XII th Congress of th International Union of the Prehistoric and Protohistoric Sciences, we presented the restoration of a shoe discovered in Baia (photo 2,3). This time we present the preservation of two leather - fragments. The first of them is a sample in the shape of a trapezium size cm 25X20 cm (photo 4). We can easily see that it was negligently cut out, and it has unequal orifices on three of its sides. Probably, these orifices are useful for introducing a cord through them. Parallel to one edge of the sample, we see a neat stitch, which contrasts which contrasts with the cut and the rudimentary orifices. We have not the other side of the sample, so we can't specify its destination. We think that it was an armour support. The future excavations will give us the answer. The leather is dehidrated, craked and ragged (photo 5,6). The second sample is a shoe sole (photo 7), 10,6 cm in lenght and 5,1cm in breath. It was carefully cut out from a thin leather. It is a little asymmetric, and its destination was to cover the right foot. This sample is better preserved than the first one, it presents a fissure to the point and also the absence of the point. At the beginning, we performed a dry cleaning by using folding magnifying glasses and a series of tools, brushes, medical micro - curettes, which enables us to remove part of the earth tightly adhering to the objects. A wet cleaning followed, with the view of removing the dust and other impurities. Using cotton-swabs introduced in distilled-water 80
