Goldau

surface prep

The paper should be dry and free from dampness to prevent the sizing from fermenting and losing its properties (Source 1). Ideally, the paper should be made from linen rags and bleached by pure water, air, and sunshine, though modern high-quality cotton rag paper is the accepted equivalent. The sizing should be evenly distributed within the paste, not just on the surface, to prevent irregular sponginess and stains during prolonged work (Source 1).

underdrawing

Turner was trained in topographical drawing and perspective, having served as an architectural draftsman and professor of perspective at the Royal Academy (Source 5). While specific underdrawing techniques for 'Goldau' are not detailed in the sources, his early discipline involved copying major topographical draughtsmen to perfect drawing skills (Source 2). It is likely that a precise initial drawing was made to establish the landscape's structure, which was then obscured by atmospheric washes.

underpainting

Turner’s watercolor technique often involved a mixture of transparent washes and opaque body colors (Source 1). The process likely began with transparent washes to establish the general tone and atmospheric mood, reserving the paper for lights (Source 1). This aligns with the 'wise simplicity of method' he learned from Dr. Monro (Source 2).

Mixing transparencies and opacities

Turner’s watercolor style included impastements, opacities, and transparencies, creating a complex visual effect that went beyond simple washes (Source 1).

Atmospheric effects

Turner used watercolor to convey mood and atmospheric illusions, particularly in Alpine views, showing the true potential of the medium (Source 2).

Use of unstable pigments

Turner experimented with a wide variety of pigments, including carmine, despite knowing they were not long-lasting, prioritizing the fresh appearance of the work (Source 2).
