Infinity Squared by Christopher Gryder. Ceramic relief wall tiles formed by carving a dissolvable mold from silt, casting clay within, and excavating several days later. Glazed and fired with colored terra sigillata. Suitable for either interior or exterior installation. The assemblage is comprised of 9 tiles. Each tile (8in x 8in x 1.5in) can be hung on the wall with a simple hook or nail, similar to that used for hanging framed artwork.
