The present work, as one of the first scientific works, deals with the modification of the glass surface induced by DCSBD plasma discharge to increase the adhesion of decorative gold layers on glass products. In the study of such a modification, it was necessary to monitor the effectiveness of the modification of the glass surface, and subsequently it was necessary to test the resistance of the deposited gold layers in tests performed directly in operation. In the present work, the adhesion of gold to DCSBD-modified glass surfaces by plasma discharge was uniquely evaluated by image analysis.
