Glass has been smelted in what is now the Czech Republic since ancient times. The first workshops of glassblowers appeared here at the end of the 13th century in the area of the Giant Mountains. Glass production technology improved, and by the end of the 17th century, Bohemian glass began to successfully compete with Venetian glass, a recognized leader in this field.
Bohemian glass, unlike Venetian glass, was harder and easier to cut and engrave. Over time, lead oxide began to be introduced into the composition of the glass mass, due to which Bohemian glass acquired a special transparency and radiance, similar to iridescent glare on the edges of rock crystal.
The works of the Bohemian masters were distinguished by the skillful engraving known as Tiefschnitt.
In the 19th century, a number of specialized schools were founded to continue the traditions of this craft, the largest of which was in Kamenitsky Shenov (Steinschenau) since 1856.
Engraving was also taught in glass factories such as the Moser factory in Karlovy Vary. Several talented engravers opened their own engraving studios, such as Carl Pietsch (1828-1883), who studied with Franz Zahn and the Pelican workshop and worked independently in Steinschenau, supplying J&L Lobmeyr in Vienna with specially commissioned exhibition quality work.
Glass engraving was carried out with an abrasive wheel or a diamond cutter. Typically, the engraved surface remains matte, allowing the engraved design to show through on the transparent surface of the glass.
