Plastilina is a wax- and oil-base modeling material used by sculptors for modeling pieces. Plastilina can also be referred to as plasteline, plasticium, and plasticine. The main ingredients are wax, oil, and clay flour that is used as a binder. All plastilina is produced hot, and then cooled and extruded into the shape that will eventually be available for sale in art supply stores. There are basically three groups of plastilina: professional grade, school grade and industrial grade.

The professional grade plastilina commonly contains sulfur, to make the smoother, more homogeneous texture required by professionals. ROMA Plastilina is an oil- and wax-base modeling material preferred by professional sculptors. A non-sulfur professional grade material in medium consistency, called Prima Plastilina, is also available.  

The school grade, or amateur grade plastilina, does not contain sulfur and tends to be stiffer and harder to model with the fingers. School grade plastilina comes in a variety of striking colors and is used in the Claymation field of movie production and advertising.

The industrial grade plastilina is usually very hard and needs to be heated prior to use. This type of plastilina is most commonly used by designers in the automotive field for car models and is not available to the retail consumer. The large auto companies use batch lots of this plastilina in large quantities of 2,000 pounds or more; the plastilina is so hard it cannot be modeled at room temperature.  

Plastilina is used as a modeling material only and cannot and should not be fired in any way. Plastilina cannot be made permanent. A mold of plaster or rubber must be made to obtain a finished piece.
