surface prep

The surface must be prepared with a ground, typically gesso or a mixture involving Chinese white, to ensure the silver leaves a visible trace (Source 2). Leonardo’s practice, as described in Susan Dorothea White’s work, involves specific preparation of the ground to receive the metalpoint (Source 2). The ground should be smooth and slightly textured to hold the silver particles. Modern artists often use commercially prepared video media paper or casein-coated parchment, but for historical accuracy, a gesso-based ground is appropriate (Source 1, Source 2).

underdrawing

Silverpoint is a direct drawing technique; there is typically no separate underdrawing phase in the same way as oil painting. The silverpoint itself serves as the primary line work. However, the artist must rely on a keen sense of construction and anatomy, as the medium does not allow for easy erasure (Source 5). The lines are definitive and require confidence in placement.

underpainting

Not applicable. This is a drawing, not a painting. Silverpoint relies on the oxidation of the silver over time to deepen the tone, rather than layered paint.

Silverpoint drawing

Dragging a silver rod or wire across a prepared surface to create fine lines. The technique relies on the softness of the metal to leave a mark that oxidizes over time.

Anatomical construction

Using knowledge of the skeleton and muscles to build the form from the inside out, ensuring the external appearance reflects the underlying structure.

Line rhythm

Using lines to direct the viewer’s eye and create a harmonic sense in the drawing. The lines should have a 'music' to them, guiding attention to key areas.
