You can see some of these inconsistencies in the image to the right: - Areas of black and white show how manually glass beading does not cover the part consistently over all the surfaces.
- Corners and edges have residue powder.
- Repeated manual operations soften the ideal sharp edges
- Dimensional variations occur because of nonuniform removal of powder.
