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."
