Ampersand Art Supply developed the most advanced formula for sealing wood to ensure that their painting grounds and your artwork remain acid-free over time. In fact, every Ampersand Museum Series panel features their Archiva-seal logo! Ampersand's Museum Series painting surfaces are a joy to paint on. They make paint colors brighter and more luminous than paper, canvas or even other panels. Unlike other hardboards and MDF boards, the Hardbord™ that they use is made without formaldehyde or harmful VOC's (volatile organic compounds). Claybord™, Gessobord™, Encausticbord™, Aquabord™, and Pastelbord™ are all made with grounds that are archival and non-yellowing! All Museum Series Panels (Claybord™, Gessobord™, Encausticbord™, Aquabord™, Pastelbord™, and Scratchbord™) are made in the USA! |
