Scraping highlights into dried ink washes, erasing passages in colored pencil down to fresh starts, building up and removing acrylic until composition resolves.

The pH-neutral hardboard backing provides dimensional stability that paper cannot match. No buckling under wet media, no surface damage from aggressive erasing or scraping tools. Ampersand bonds museum-grade kaolin clay in a smooth, toothy coating that grips graphite, ink, watercolor, gouache, and oils with equal receptivity. Professional illustrators value this when client revisions demand significant changes without starting over.

Twelve years of artist Charles Ewing's experimentation refined this surface specifically for working methods that involve substantial correction and refinement. Whether you're developing complex illustrations through multiple iterations or exploring subtractive techniques that reveal white as part of your image, Claybord handles the physical demands that destroy conventional surfaces.
