The Scratchbord from Ampersand is a clay coated hardboard panel, coated with Indian Ink - produced for scratchboard techniques. Comparable to traditional scratchboard made from paper, except better - it's more durable and easier to scratch into for cleaner-crisper details and lines. For greater or added dimension, coloured inks can also be added to the white areas and then scratched again, for additional highlights and volume. The 3mm (1/8inch ) deep Scratchbord range includes a variety of sizes, from 12.7 x 17.8cm (5 x 7inch ) through to 27.9 x 35.6cm (11 x 14inch;). Sizes
