that the following slabs, which were joined together, overlapped each other. On the top of the sherd the slabs overlap each other in a length of 2.2 cm, while on the bottom of the sherd the length of overlapping is ca. 2 cm. The vessel was finished on a slow wheel. The examined sherd is probably a slab itself because it seems to be reduced all around in its cross sections. Thus the edges of the slab were reduced during firing as a result of breakage of the vessel. The fabric of the sherd shows increased amount of sand. The majority of quartz grains are opaque and white showing up to 1 mm in size although sparse amounts of coarse quartz up to ca. 2 mm could also be identified. Maximum height: ca. 7.2 cm, max. width: ca. 6 cm, thickness range: ca. 0.8-1.1 cm. 16. Inv.No. 722.378.5.2 (Fig. 6/4): It is a light brown body sherd of an amphora with a rib decoration. The sherd is oxidised on its exterior and interior although fire clouding is also present on both its exterior and interior. The vessel was built using the slab technique. In this sherd the joining of two slabs were identified. In the interior of the sherd there is a clearly visible straight line where the slabs were joined. In the cross section of the sherd it could also be observed that the slabs did not overlapped each other, they were simply attached together. The sherd itself is ca. 4.3 cm high slab to which another ca. 2 cm high slab was attached. Shorter slabs are usually attached to larger slabs where there is a sudden change in vessel curvature. In this way a shorter slab accommodates abrupt change in vessel curvature because this is the part of a vessel where stress accumulates during drying and firing. The vessel was finished on a slow wheel or tum table. The fabric of the sherd shows increased amount of sand. The majority of quartz grains are opaque and white showing up to 1-1.5 mm in size. Maximum height: 7.4 cm, max. width: 7 cm, thickness range: ca. 0.7-0.8 cm. 17. Inv.No. 722.378.5.3 (Fig. 6/5): It is a dark grey body sherd of an amphora with two parallel rib decorations on its exterior. Straight below the ribs there are shallow smoothed channels. The sherd is reduced on its exterior and interior. The core is irregularly fired. The vessel was built using the slab technique and the slabs overlapped each other. The vessel was finished on a slow wheel or turn table. The overlapping area of the slabs on the top of the sherd is ca. 2.6 cm, on its bottom is ca. 2.4 cm. The fabric of the sherd shows increased amount of sand. The majority of quartz grains are opaque and white showing up to 1-1.5 mm in size. Maximum height: ca. 7.2 cm, max. width: ca. 6.5 cm, thickness range: ca. 0.8-1 cm. 18. Inv.No. 722.378.9.1 (Fig. 6/6): It is a light brown body sherd of an amphora. The sherd is oxidised on its exterior, interior and core although red and black patches of fire clouding are present on its exterior and interior. The vessel was built using the slab technique. The joining of two slabs was identified; they were simply pressed together without overlapping each other. The upper part of the sherd shows a ca. 6 cm high slab. Because of the fragmented nature of the sherd the size of the other slab could not be assessed. The vessel was finished on a slow wheel or turn table. The fabric of the sherd shows increased amount of sand. The majority of quartz grains are opaque and white showing up to 1 mm in size although sparse amounts of coarse quartz could also be identified. The majority of the coarse quartz are up to ca. 2 mm in size. Maximum height: 11.5 cm, max. width: 11.7 cm, thickness range: ca. 0.6-0.9 cm. 19. Inv.No. 722.378.9.2 (Fig. 6/7): It is a light brown and dark grey body sherd of an amphora. The sherd is irregularly fired on its exterior, interior and core. The vessel was built using the slab technique and the slabs overlapped each other. This is indicated by the two layers present in the cross section of the sherd. The sides of the sherd are fairly straight that may indicate that the examined sherd was itself one slab. The vessel was finished on a slow wheel or turn table. The fabric shows increased amount of sand. The majority of quartz grains are opaque and white showing up to 1-1.5 mm in size. Rare amounts of red iron oxide are also present. Maximum height: 7.1 cm, max. width: 7.1 cm, thickness range: ca. 0.6-0.7 cm. 20. Inv.No. 722.378.9.3 (Fig. 6/8): It is a light brown and grey body sherd of an amphora with a shallow smoothed channel decoration. The sherd is irregularly fired on its exterior, interior and core. The vessel was built using the slab technique and the sherd is itself one slab. In the upper part of the sherd a further slab was joined to it by the overlapping technique and the squeezing movements of the fingers are clearly identifiable where the two slabs were attached together. The pressing movements of the fingers as the two slabs were squeezed together created micro cracks on the interior of the vessel, which are clearly visible. At the bottom of the examined sherd another slab was joined but they did not overlap, they were simply attached together. The vessel was finished on a slow wheel or turn table. The fabric of the sherd shows increased amount of sand. The majority of quartz grains are opaque and white showing up to 1 mm in size although sparse amounts of quartz with up to 3 mm are also characteristic. Maximum height: 6.2 cm, max. width: 10.4 cm, thickness range: ca. 1.2-1.5 cm. 21. Inv.No. 722.378.9.4 (Fig. 6/9): It is a dark grey body sherd of an amphora with a shallow smoothed channel decoration. The sherd is reduced on its exterior
