A large (104 cm tall by 78 cm wide) wooden plaque depicting the periodic table. The artifact was designed and fabricated for the Canadian Nuclear Society (CNS) by Dave Morrison in 2004 and features, wherever possible, sample vials of the elements on the table. Where samples are unobtainable because the elements are gases, very toxic, radioactive or are metals unstable in air, photographs of the material are used in the vials. Those elements that have such short half-lives that even photographs of samples cannot be obtained are denoted by the nuclear trefoil.
