Polishing – After a stone is shaped, how facets are polished. In this tutorial, these procedures are explained as well as a brief description of a faceting machine and a diagram. Faceting Machine. Each facet is cut by grinding a rough stone on a flat round file called a lap. The lap turns around horizontally in a faceting machine.
As flakes are detached in sequence, the original mass of stone is reduced; hence the term for this process. Lithic reduction may be performed in order to obtain sharp flakes, of which a variety of tools can be made, or to rough out a blank for later refinement into a projectile point, knife, or other object.
