The products made of hand-engraved crystal are the materialization of an amazing skill that brings various pictorial motifs into the purest crystal. The combination of the high level of craftsmanship of the engraver, cutter, glass blower and designer is the decisive factor for this art that knows no limits and can thus create fascinating images on lead crystal with the same detail as, for example, classical paintings.
Engraving is another mechanical process of glassworking, which is very similar in technique to glass cutting, but instead of grinding wheels, small vertically positioned discs are used, to which water and possibly abrasive is fed. The coarseness of the engraved surface can vary based on the hardness of the abrasive or the size of the wheel. The engraving technique has three basic variations. The most complex is relief engraving, either in depth (negative engraving) or in space (relief engraving). This ancient technique has its roots in ancient Rome, where semi-precious stones, called gems, were decorated by engraving and cutting. Initially, flat glass was engraved, gradually hollow glass was also engraved. Drawings and ornaments were also added. Today it is also used in glass sculptures. Engravings are considered to be one of the most elaborate techniques for depicting various motifs in detail, whether figurative or zoomorphic. Engraving can be: 1. Sculptural, also called a cutting technique, originally crystal. 2. Linear, demanding precision, it is also used for lettering. 3. Sliding, the most common today. Uses electrite discs. 4. Stripped, used to achieve colour transitions in glazes. 5. Copper engraving is the engraving of a loose abrasive applied to a copper disc using a wetting fluid (oil, kerosene). 6. Hand engraving with a diamond or diamond point.
Cutting glass with rich decor is a traditional handcrafted technique of decorative glass refinement. Cut glass is used as a decorative technique for decorating vases, bowls, flat trays, decanters, bottles, baskets, table drinking glass and other shapes of practical use.
It is practically cutting into the surface of a glass object. From a sampling of glass and individual cuts, the final image is composed and "modelled". Like a painter's brush, a sculptor's chisel or a printmaker's chisel, the engraver's tools are rotating wheels, most commonly copper, carborundum, electrite and diamond wheels. As the engraver works, he applies a thin layer of emulsion of emery powder and kerosene, pure kerosene or water to their circumference, forming a cutting wheel that can remove the hard mass of the glass and leave the necessary matte mark on it.
