Abstract
The influence of the local coordination on the Pb++ mobility has been studied by EXAFS in Lead-glaze systems with different modifier oxides. The interatomic distances and coordination numbers obtained are quite the same for all considered glazes. The different Pb++ mobilities cannot be related to different elastic stresses of the Pb-0 bond.
