A number of methods can be employed to engrave glass. Line, or Point Engraving, with a diamond or tungsten carbide point, scratches the surface. Stipple engraving, using the same tool, can be used in the design and helps to vary tone. Drill engraving can cut more deeply, giving a three-dimensional effect. Sandblasting is used with hand-cut stencils and deep cutting and shading.
The final result from a skilled artist can capture light and portray images which often possess an ethereal, almost mystical effect.
