Engravers of this period progressively deserted direct clearness in favour of crosshatched chiaroscuro effects. A few engravers, such as Schongauer and Mantegna, took care of glass with a sculptural sensation.
Old Art
By the end of the 17th century, however, diamond-point engraving was being replaced by wheel inscription. Two notable engravers of this duration deserve mention: Schongauer, who elevated the art of glass inscription to match that of painting with jobs like Saint Anthony Tortured by Demons, and Mantegna, that shaded his drawings with short jotted lines of varying width (fig. 4) to attain chiaroscuro impacts.
Other Nuremberg engravers of this time consisted of Paul Eder, that excelled in fragile and little landscapes, and Heinrich Schwanhardt, who engraved engravings of fine calligraphic top quality. He and his kid Heinrich likewise developed the strategy of etching glass with hydrofluoric acid to produce a result that looked like glass covered in ice. The etched surface area might then be reduced and engraved with a copper-wheel. This approach is utilized on the rock-crystal ewer shown below, which integrates deep cutting, copper-wheel engraving and sprucing up. Identifying the inscribing on such pieces can be difficult.

Ludwig Moser opened a glass style workshop in 1857 and achieved success at the Vienna International Exhibition of 1873. He established a totally incorporated manufacturing facility, offering glass blowing, polishing and engraving. Till completion of The second world war, his firm dominated the marketplace of personalized Bohemian crystal.
