This booklet regularly comprises contributions by means of the invited academics on the seventh overseas convention on Non-Destructive trying out and Micro-Analysis for the Diagnostics and Conservation of the Cultural and Environmental background. The participants have all been selected for his or her person reputations and the standard in their study, but in addition simply because they signify a box deemed hugely vital. for that reason, this e-book provide balanced insurance of the components which are so much proper in non-destructive checking out and micro-analysis within the realm of cultural history. The research equipment give you the scientific composition of cultural artifacts to explain their provenance, the speed of alteration because of publicity to the surroundings and the effectiveness of conservation and recovery techniques. The innovations are partly or totally non-destructive, are moveable, or permit learn of alternative elements of a heterogeneous murals.

4 Interpretation of grey values A series of glasses with different compositions was measured to determine the range of grey values for non-corroded glass. As expected, the strongest attenuation was observed for glasses containing lead. Bulk material of “SiO2 ”, prepared by the sol-gel process, was resolved as a compound with very weak attenuation. All other glasses yielded values between those two extremes. 1 Selected results Figure 8 shows an mCT image of a model glass for which the characterization by SEM is presented in Figure 6.

000 years. They were made both for daily use and for artistic purposes. Historic glasses – especially those originating from antiquity and the Middle Ages – are mostly retrieved from archaeological excavations. The largest part is represented by vessel glass and glass jewels, rarely found as entire pieces but mostly as fragments (Newton & Davison 1989, Knight 1996). Outstanding objects are presented in museums or private collections. The rearrangement of fragments to form a complete object is often not successful.
