Sculpting Clay
by Special Effect Supply

There are two basic kinds of sculpting clay, Oil Based Clay and Water Based Clay. All Oil based clay is sulfer free.

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.

Klean clay has gone the way of the Earth. The old gentleman who made it used up the last of his chemicals and retired. He did, however, sell his formulas and equipment to a competitor, who has taken up the cause. The replacement clay is as follows:

Industry note: The prices on almost everything we sell has gone up. Prices for raw
materials have shot up and so has shipping. Most of my industrial suppliers have absorbed these increases, but they can't do this forever. The main complaint has been the cost of oil and resins.

Sulfur free. Can be melted to a liquid and poured into a mold including alginate. Unless you specify otherwise, a neutral color such as flesh, tan, grey or the like will be shipped. Very soft. [Color Code]

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.
