The block of stone as received from the quarry, with the small clay model, and the rough outline of the form drawn on the stone.
The bulk of the stone has been removed with the use of a diamond wheel on a high-speed grinder, cutting slots in the stone, which is then removed with hammer and chisel.
Further shaping with the use of pneumatic (compressed air) chisels.
Grinding wheels (diamond and carborundum) are used to refine the shape and start smoothing the surfaces.
5: With further smoothing and then polishing, the natural colour of the stone emerges. The contrast between the polished surfaces and the textured surfaces (e.g. the hair) is obtained by leaving some of the stone unpolished, giving it its white appearance.
