Project Instructions

Getting Started: Please make sure your work area is covered and you are not working on an unprotected surface. We recommend working on the Sculpey® Oven Safe Work Mat, wax paper, metal baking sheet, or disposable foil. Uncured clay may damage unprotected furniture or finished surfaces. Be sure to cover your crafting area appropriately. Start with clean hands, unwrap and knead clay until soft and smooth, or condition by running clay though a Pasta Machine. We recommend using a designated machine for clay purposes only. When working with multiple colors, clean hands with soap and water or baby wipes (we have found that baby wipes work best) before switching colors. Shape clay, pressing pieces firmly together. Wash hands after use. Baking: Begin by preheating oven to 275 °F (130 °C). After you are done creating; for best results bake clay on an oven-proof surface such metal, aluminum foil, an index card or the Sculpey® Oven Safe Work Mat at 275°F (130 °C) for 30 minutes per 1/4" (6 mm) thickness according to package directions. Oven safe glass or ceramic surfaces are also acceptable for baking; however please note that the baking times may take longer as the glass or ceramic surfaces take longer to heat up. For best baking results, use an oven thermometer. DO NOT USE MICROWAVE OVEN. DO NOT EXCEED THE ABOVE TEMPERATURE OR RECOMMENDED BAKING TIME. BAKING SHOULD BE DONE BY AN ADULT.
To prep the planter, paint 2-3 coats of glossy white acrylic paint on the outside of the pot. Glossy acrylic paint not only makes a nice finish but it also provides a background surface that the raw clay will easily stick to. Allow the paint to dry completely.
From the sheet of Granite Marble Slab that we made in the Granite Marble Slab Earrings Tutorial, cut out several small, medium, and large circles.

Press these randomly to the sides of the planter. The glossy paint background will hold the clay circles in place.

Bake the planter following the baking instructions for Sculpey PremoTM. Allow to cool completely before handling.
