SAMPLES OF ENGRAVING ON BASALT
Basalt is ideal for engraving, as it has a uniform structure. Basalt is mined in western Ukraine, as well as imported from China. Basalt is soft enough, so the engraving step is usually set at 0.300..0.350mm.
On basalt, due to the lack of inclusions, the same contrast retouching is not required as on a gabbro. When one pass is enough while engraving.
