Oil Based Clay
Oil based clay is clay mixed with some kind of oil or combinations of oil. It will not dry out, but it will oxidize over time and become difficult to work. Sometimes you can manipulate the consistency of the clay by mixing it with petroleum jelly, but this is hard work. Some oil based clays like plastina contain sulfur and can't be used with silicone molding compounds. Plastina can be sealed with a coating of sealer or shellac but any coating of this type will take away some of the character of the clay. We recommend and use an industrial tooling clay which is easy to work and won't react with silicones. Some oil based clays can be melted and poured into a mold. Preheating oil based clay will soften it and make it easy to work.

Original Sculpey is the modern modeling compound that stays permanently pliable at room temperature. It's non-toxic, smooth, non-sticky, non-staining, and won't shrink. When placed in an ordinary home oven at 275°F (130°C) for 15 minutes per ¼" (6 mm) thickness, it becomes permanently hard, and won't crack, chip, or crumble. After baking, Sculpey Modeling Compound can be sanded, carved, rebaked, and painted with acrylic paint or other water-based colors. Glaze the baked surface with Sculpey Glaze.
Instructions are included. Available in White. Made in the USA.
Oven Bake Polymer Clay
Sculpey III clay has the same excellent handling qualities of Sculpey and Super Sculpey, combined with the dimension of color. It bakes to hardness in a 275 degree Fahrenheit oven in 15 to 20 minutes. A finish can be applied with Sculpey Glaze in either gloss or matte. Sculpey III is an excellent medium for jewelry, maquettes and miniatures. Once baked, its hardness makes it great for making a two-part silicone mold. The bars are small so pay attention to the 2 oz (56g) size. Dimensions of each bar are about 1 3/4" x 3/4" x 2 1/4"
