Sculpting Clay

There are two basic kinds of sculpting clay, Water Based Clay and Oil Based Clay.

Water Based Clay

Water based clay is simply that, clay mixed with water. It is usually very inexpensive but must be kept covered or it will dry out. Water based clay is easy to work when it has just the right amount of water, which is easy to manipulate. It is easy to remove from a mold with a water sprayer. Its disadvantages are equal to its advantages; it is often hard to control especially if a project goes into many days, it sags and separates easy, and it can't be used with plastics, epoxies or polymers.

NOTE: We no longer sell water based clay. It is easy to obtain locally at your local art store and many craft stores. You can usually buy twice as much for the price you would have to pay me for shipping it.


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. A pound of Klean clay is about 3 3/4" x 7/8" x 5 3/8."

About 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"


Sculpey III Oven Bake Polymer Clay, 2 oz Bar (56g)


Specify your color choice from the following; White, Trans, Green, Sweet Potato, Black, Chocolate, Blue, Yellow, Red, Beige, Pearl, Pink Pearl, Lt Blue Pearl, Lilac, Blue, Green, Copper, Red Gold, Gold, Silver, Tan, Dusty Rose, Teal, Lavender, Leaf Green, Emerald, Terra Cotta, Navy Blue, Maroon, Coral, Ivory, Hot Pink, Turquoise, Purple, Violet, Lime, Mint, Atomic Orange, Lemon, Red Hot Red.
