Original Abstract

This work focuses on the removal of corrosion product layers from the glass made archaeological artefacts. The reactive species and physical effects generated by the underwater discharge in multielectrode configuration were used as reducing agents. Original archaeological artefacts were treated for three minutes per square cm at the applied power of 5 W. Surface changes were visible by the naked eye and visualized using scanning electron microscopy. The relative concentrations of the elements were monitored by X-ray microanalysis on the objects surfaces and from the object core. Very good corrosion removal using this new low stressing technique was fully confirmed.
