Instructions
Wet the clay and wedge it to remove air pockets. Wedging is important, because if bubbles remain in the clay, it may explode when it is fired later. To wedge, lift the clay and slam back down onto a table or other flat surface for 10 minutes.
Make the rocks. For each one, pull off a piece of clay and shape it into an oblong, tall and sharp or rounded rock.
Make the caves. Unlike the rocks, the freestanding caves will be hollowed out. For each cave, take a piece of the clay and flatten it to a thickness of about ½-inch. Then mold into a shape with a flat bottom and a rounded top. Fish will use the cave to hide in, so it needs at least once entrance. Since the clay is still soft, use a pottery toolkit containing a wooden knife or trimming tools to make a hole in the clay for the entrance.
Etch and mark the outsides of the caves and rocks, using clay shaper tools available from pottery- or art-supply stores. Make creases and crevices to resemble real rock.
Allow the pieces to air dry overnight. The following day, the clay will still be soft enough to add more markings or entrances to finish the pieces, if needed.
Fire the clay in a kiln. Kilns are available for home purchase but are several hundred dollars. Inquire at local art-supply stores about places that provide access to kilns for a fee.
Use lead-free ceramic paint to paint the pieces. To make natural-looking rocks and caves, paint on mosses and shadows.
