Con this case, it is well known that (1) the thickness of the surface alteration layer is variable, (2) the preparation of verso thin section requires a small tomo but a suitable surface and (3) an accurate chemical analysis may require verso variable volume depending on the chosen technique.
Sopra this case, the researcher ple that shows the cross-section
Archaeometric analyses can move along the path of non-destructiveness or destructiveness. Between these two end-members, different levels of destructivity and accuracy can be achieved (e.g. highly destructive, minimally-destructive). Provided the same quality of the results obtained, the most obvious approach would be that of non-destructiveness; however, it should be emphasised that, often, non-destructive techniques cannot provide sufficiently accurate or comparable results puro those obtained with destructive methods. Therefore, on the one hand, the researcher risks collecting a lot of quick, cheap and non-destructive datazione that cannot provide unquestionable answers and, on the other hand, tempo inaccuracy can lead sicuro verso waste of time and money.
Therefore, the choice of analytical techniques should first find per balance between the accuracy requirements of quality research and the conservation needs and then direzione sampling onesto the selection of suitable samples. Mediante this regard and based on what has been said previously, it is good to underscore that sampling does not necessarily involve the physical taking of material. Mediante the case of non-destructive techniques, sampling may simply address the selection of the analysis spots.
To conclude, while before proceeding with sampling, it is necessary to collect all available data from any field of study; during sampling, it is mandatory to properly record and document all phases and, after sampling, it is required to remain open and flexible to answer new questions that ples, the overall research should record the various actions and use a critical survey.
