Ampersand Museum Series Claybord is made from 3mm high-density artist hardboard using Aspen wood fibers, with an absorbent kaolin clay ground and a handcrafted 13-ply birch plywood cradle. The archival, formaldehyde-free panel is protected by Ampersand’s Archival-Seal barrier to help prevent support-induced discoloration. It is available with a 22mm or 38mm cradle and supports ink, egg tempera, acrylic, casein, watercolor, gouache, pencil, pen, airbrush, collage, photo transfers, printmaking, and mixed media.

The smooth clay surface allows paint and ink to be removed, reapplied, scratched, sanded, or erased to adjust tonal values, create highlights, correct mistakes, and add fine details. The cradle can be painted, stained, or primed with gesso, while the 38mm profile fits standard canvas and floater frames. Very thin glazes or washes may reveal faint circular sanding marks; for an exceptionally smooth surface, prepare the panel with very fine sandpaper or oil-free steel wool before use.

This is an 8 x 8in cradled 22mm Ampersand Museum Series Claybord Panel.
