Glittery Wavy Nested Ring Dish

Condition each color until it is smooth and pliable, then mix fine iridescent glitter thoroughly into the pink, yellow, and blue batches so the sparkle is even. Roll each color into a flat slab of one even thickness against your thickness guides (a medium slab is common for a small dish), rolling, flipping, and rotating so it stays one thickness end to end.

Pattern option A - nested wavy rings: use a graduated set of wavy or scalloped circle cutters to cut a solid pink center and concentric wavy rings, then nest them around the center in the photographed order (pink floor, thin blue, pink, thin blue, yellow, thin blue, yellow at the outer edge). Wipe the touching edges with a damp swab or a brush of isopropyl alcohol, then press the seams together firmly so they bond.

Pattern option B - cut-and-joined strips: cut straight strips of each color (wide pink and yellow with thin blue separators between them), lay them edge to edge in order on your work surface, and press the seams together. This gives the same banded read and is easier than cutting many concentric rings.

Pattern option C - stacked and sliced: stack the conditioned colors into a layered block in the band order, let it firm, then slice thin cross-section sheets that show the stripes and lay them onto a base slab. This gives the most repeatable, crisp band pattern.

Lay parchment over the patterned assembly and roll gently in several directions with the acrylic roller to weld the seams into one seamless slab. Keep the whole slab at one even thickness so it cures evenly and the rim does not slump. Cut a clean circular blank with the round cutter.

Dust the inside or the outside of your oven-safe bowl form with cornstarch as a release so the cured dish lifts off cleanly.

Form option A - drape over the outside: set the bowl upside down and lay the blank over the dome, smoothing from the center outward to push out air, letting the slab fall into the curve, then trimming the rim level. This gives a smooth convex underside and an easy-to-trim rim.

Form option B - press inside: ease the blank down into the dusted bowl and press it gently against the floor and wall so it takes the curve, working wrinkles out toward the rim. This gives the smoothest concave inside, which is the surface that shows the most.

Shape the scalloped rim by easing the wavy edge into 6 to 8 even peaks around the perimeter, working both sides evenly so the rim keeps its rhythm. Keep the floor an even thickness as it stretches over the curve.

Smooth the inside while the clay is still raw: press out fingerprints and seams with a fingertip or firm silicone shaper, then lightly brush isopropyl alcohol or a damp finger over the surface to melt small marks. Soften the cut rim edge with a fingertip so it is smooth to the touch.

Bake the dish on its form so the curve and the wavy rim hold their shape, at your clay brand's package temperature and time scaled to the slab thickness. Set the form on the center rack on a flat surface (cardstock, a ceramic tile, or foil), away from the elements, and tent loosely with an inverted foil pan so the high rim does not scorch before the floor cures. An oven thermometer confirms the real temperature.

Let the piece cool fully on the form before releasing it, since warm cured clay is still soft and a curved dish can deform if you lift it too early.

Once cooled, wet-sand any rough spots on the scalloped rim through 600 then 1000 grit and buff with a soft cloth. For shine, brush a thin even coat of a polymer-clay-compatible satin or water-based polyurethane finish, tested on baked scrap first; build it thin so it adds sheen without burying the glitter. This finish is decorative shine, not a food or liquid barrier.

Use the dish as a decorative catchall for rings, earrings, keys, and small jewelry. Cured polymer clay is porous and is not made for food contact, and sealing it does not change that, so keep it to dry, non-food items.
