My mobiles are made primarily from rolled slabs of stoneware clay that are cut into triangles, squares or hexagons. Their edges are beveled to correspond to the dihedral angles of each solid form and then joined with slip. I make cardboard frames to help support the larger pieces during construction. I frequently apply colored slips or engobes to the leather hard pieces and decorate the surface using sgraffito and Mishima techniques. The individual elements are fired to cone 10 in a reduction atmosphere, although some of the larger pieces that are more likely to deform in the heat are fired to cone 5-6 in oxidation.
For the support arms, I use fallen tree branches found during neighborhood walks or I purchase extruded aluminum rods. I assemble the mobiles in my garage using simple power tools. Occasionally, I use manufactured pieces (e.g., wooden hoops, swivels, cotter pins). The ceramic elements are suspended from the arms using 100-pound monofilament fishing line. The mobiles can be hung either indoors our outdoors.
