Museum Series Claybord™ from Ampersand is a unique, specially prepared working surface perfect for use with creative materials. It is made using high quality artist hardboard & features Ampersand’s simply amazing kaolin clay ground formula similar which performs similar to the clay gesso grounds used during the Renaissance period. The surface is sanded to an ultra-smooth, highly absorbent finish so your colour or media remains true, brilliant & stable. Claybord is a favourite of both fine & graphic artists alike. Clayboard comes in a wide range of sizes from 12.7 x 17.8cm (5 x 7") through to 45.7 x 60.1cm (18 x 24"), in three different depths of 3mm (1/8"), 22mm (7/8") & 38mm (1.5").
