Engraving on glass most probably started at the time glass as an artificial material was invented. Throughout history new ways of the technique have been introduced and today there is no limit to this engaging means of expression. The book author gives an overview of the present state of glass engraving in Europe with focus on Glass Engraving Network authors, and in Estonia in particular. Historical background is also lightly touched. Mare Saare is professor emerita of the department of glass of the Estonian Academy of Arts, Tallinn.
