Established in the center East and Egypt on hardstone, copper wheel etching made it through as a craft in seventeenth century Bohemia and Dresden on glass. It was utilized for a range of purposes, including portraying the imperial double-headed eagle (Reichsadlerhumpen) and allegorical motifs.
Engravers of this duration slowly deserted direct clarity in favour of crosshatched chiaroscuro impacts. A few engravers, such as Schongauer and Mantegna, managed glass with a sculptural feeling.
Old Art
By the end of the 17th century, however, diamond-point inscription was being supplanted by wheel inscription. Two remarkable engravers of this period deserve mention: Schongauer, that increased the art of glass inscription to match that of paint with works like Saint Anthony Tortured by Demons, and Mantegna, that shaded his drawings with brief scribbled lines of differing width (fig. 4) to accomplish chiaroscuro effects.
Various other Nuremberg engravers of this time included Paul Eder, who mastered delicate and little landscapes, and Heinrich Schwanhardt, who etched inscriptions of fine calligraphic top quality. He and his child Heinrich additionally established the strategy of etching glass with hydrofluoric acid to generate an effect that looked like glass covered in ice. The etched surface can then be reduced and engraved with a copper-wheel. This technique is used on the rock-crystal ewer shown below, which combines deep cutting, copper-wheel engraving and sprucing up. Identifying the etching on such pieces can be challenging.
Venetian Glass
When Venice was a European power, Venetian glassmakers took the lead in several high value-added industries. Unlike fabrics and style, glassmaking kept a heritage of sophisticated methods. It additionally carried seeds of the attractive grandeur symbolized in Islamic art.

This made it simpler for gem-cutter to carve similarly they sculpted rock crystal. In addition, they developed a technique of reducing that permitted them to make really detailed patterns in their glasses.
This was followed by the production of tinted glass-- blue with cobalt, red with copper and light environment-friendly with iron. This glass was preferred north of the Alps. In addition, the slender barrel-shaped goblets (Krautstrunk) were likewise prominent.
Ludwig Moser opened up a glass layout workshop in 1857 and was successful at the Vienna International Exhibition of 1873. He established a totally incorporated manufacturing facility, supplying glass blowing, brightening and engraving. Until the end of World War II, his firm dominated the marketplace of personalized Bohemian crystal.
