COST Action G8 : Non-destructive Analysis and Testing of Museum Objects
COST Action G8 (2000-2004) aims at creating a Europe-
wide network that would enable co-operation
and interaction between two groups of professionals:
people directly concerned with the maintenance of
our cultural heritage – conservators, curators, art historians,
archaeologists – and analytical scientists, including
chemists, physicists, geologists, metallurgists, mineralogists
and microbiologists. The main objective of
the action is to improve preservation and conservation
of our cultural heritage by increasing knowledge of
museum objects through non-destructive analysis and
testing. The scientific activities of COST G8 include organising
short-term scientific missions to train scientists
of both groups in the other's field as well as to
transfer practical experience among the European
countries. Regular meetings in the form of workshops
are organised in order to exchange the obtained knowledge
in a broader group, and six working groups are active,
which allows close collaboration in a specific field
In-situ spectroelectrochemical studies of the removal of chlorides from copper
This paper describes corrosion potential measurements of corroded copper samples taken whilst acquiring timeresolved
X-ray diffraction or X-ray absorption data in a synchrotron beam line. The surface structure of the samples
and its evolution, whilst under simulated conservation treatment in sodium sesquicarbonate, were examined
using X-ray diffraction. The fluid chemistry over the sample was monitored during identical experiments using
X-ray absorption. All measurements were carried out with the sample immersed (i.e. without the need to expose
the sample to air). Processes were followed from initial wetting of the surfaces through to the cessation of measurable
change. A webcam was used to make a simultaneous visual record of the sample and its environment. The
experiments aim at contributing to the improvement of conservation methods for cupreous artefacts recovered
from marine environments
