Unresolved questions on aged paper

Graphite diagrams, ink swatches, and coffee stains left on the workbench while the Prussian blue slowly dries in the late-afternoon sun.

Notebook folios

Scraps, ink, and pencil notations

Six detailed scans from working sketchbooks recording material experiments and chemical reactions.
