## 9 Conclusions and Proposals for Future Research
Magnetic field measurements in larger curvature fragments can be performed with shorter-length sensors. However, in any case, it is a small number of fragments with characteristic curvature, which are easier to categorize and assemble empirically. The apparatus is recommended to be used for the location and assembly of unidentified fragments from medium-size vases (basins, hydries) or larger-size (usually pithos vases), which are the most common excavation findings. In medium-size vases, which display a variety of shapes due to their different uses, the risk of deformation during drying is minimized with the admixture of aggregates, depending on their shape and size. The possibility of finding medium sized pots of the same clay fired in the same kilin in the same excavation layer is small. In the event that the measured magnitude shows similar values, the above applies. Regarding large size vases for storage use, these were fired in one-use kilns built around the vase, from antiquity to today. Therefore the possibility of two large vases from the same clay to have been fired in the same kiln is very small. The methodology can be used to screen fragments from archaeological excavations under the following conditions:  
* Finding co-belonging fragments of the vase base is essential for calculating the magnetization deviation angle, \(\gamma\), and the parameters \(\alpha^{\pm}\), \(\alpha^{\!/\! }\), \(\lambda\) from measurements of their magnetic field. This is not a problem, because in the usual process of screening co-belonging fragments, the base fragments, which are easily identified, are initially collected and the neighboring fragments of the vase body are then searched. * In the fragment reference system, where measurements are taken, the x-axis is oriented in the direction of the vase grooves while the \(y\)-axis is perpendicular to the surface and directed towards the inside of the fragments. To take measurements on all fragments in relation to the same reference system, the \(z\)-axis must be oriented towards the base (or the aperture) of the vase. The orientation of each fragment with respect to the base or the aperture of the vase can be done easily, on the basis of its shape and the curvature of the grooves on its surface. * Proposals for future research, based on additional preliminary investigations, are given below. 1) Experimental application of the method in fragments from archaeological excavations. 2) Construction of ceramic specimens from different raw materials and with different granulometry, fired in the same pottery kiln under different slopes of the kiln floor. * Construction of ceramic specimens from the same raw material, fired in the same kiln, with the same slope, but under different oxidative conditions and at different temperatures. * Analysis of the composition of the specimens and their content in magnetic oxides. The above are necessary in order to study the dependence of remanent magnetization on the clay composition, the temperature/ventilation conditions in the pottery kiln, the orientation of the geomagnetic field, and the degree of magnetic anisotropy of the ceramic material. For the above research a traditional wood kiln is required. In ceramic specimens made from different commercially available clays fired in an electric kiln, the measured magnetic field was less than 10 nT and without clear orientation, as a result of magnetic fields from the electric currents of the kiln. 3) Investigation of the sensitivity radii dependence of the vertical (\(\alpha^{+}\)) and parallel (\(\alpha^{//}\)) sensors on the magnetization magnitude of the ceramic material. -Investigation of the mode, the sensors' degree of excitation, and of the dependence of the normalization constant, \(\lambda\), of the vertical and parallel sensor readings as well as of \(\alpha^{+}\), \(\alpha^{//}\), on measurements of the same specimens at different distances from their surface.
