1
Step
Condition your polymer clay, selecting Sculpey Soufflé to achieve a lightweight, velvety matte surface. Dust your roller or pasta machine with cornstarch as a release agent, then roll out sheets of pink, lavender, yellow, and blue clay to an identical thickness of approximately 3 to 4 mm.
2
Step
To create the banded pattern, cut the sheets into strips, wipe the joining edges with a damp cotton swab to remove any powder, and press the edges together. For a marbled look, twist the colors together before rolling. Run a roller lightly over the joined slab to weld the seams.
3
Step
Dust your cutting tool or template with cornstarch, then cut out an oval dish blank. Dust the outside of an oven-safe bowl or dome form with cornstarch, then drape the slab over the form, smoothing it gently to conform to the shape.
4
Step
Pinch and shape the rim with your fingers to create soft, organic waves, keeping the thickness consistent around the entire edge.
5
Step
For a textured, stone-like finish, stipple the raw clay surface with a stiff-bristled brush, a coarse sponge, or a crumpled ball of aluminum foil. For a smooth finish, skip this step. Lightly dust the texturing tool with cornstarch to ensure clean release.
6
Step
Bake the dish on its support form according to the clay package directions. After cooling, gently pop the dish off the form. Keep the natural matte finish, or seal with a compatible water-based polyurethane like Varathane, avoiding any aerosol sprays or solvent-based glazes.
