Ampersand Aquaboard Museum Series Aquabord is an acid-free textured clay surface that absorbs watercolors like a fine paper. Colors retain their purity and vibrancy in a way that even the finest of watercolor papers can't match. When compared with watercolor paper, this multimedia panel simulates the absorbency and texture of cold pressed, but allows color to be lifted back to white easily while also leaving the richest, most vibrant color possible. This workable surface provides natural looking highlights, fluid glazes, transparent subtle layers, and the ability to lift color while the surface is wet or even after it is dry. Uniquely absorbent Aquabord is perfect for watercolors and gouache, but is also ideal for casein and acrylics. Will not tear, shrink or buckle even under heavy water application. Archival, eco-friendly and made in the USA. 1/8" Thick.
