plastilisel

Plastilisel is a term used in some contexts to denote a soft, malleable modelling material employed for sculpture and prototyping. Because the name is used variably, the precise composition and properties of plastilisel differ by producer, but it is generally regarded as an oil- or wax-based modelling clay that remains pliable over extended periods and does not dry hard in air.

In practice, plastilisel is closely related to plastilina, plastiline, or Plasticine; regional usage varies and some sources treat plastilisel as a family name rather than a single product. Some definitions emphasize its non-drying character and higher wax or oil content.

Most plastilisel formulations include a binder such as mineral oil or wax, optional softeners, mineral fillers, pigments, and stabilizers. The resulting material softens with kneading, can be molded into fine details, and can be remelted or reshaped as needed without curing.

Applications include sculpture, stop-motion animation, rapid prototyping, and educational demonstrations. Its pliability at room temperature makes it suitable for building models, testing forms, or teaching basic sculpting concepts.

Safety and handling are generally straightforward; non-toxic variants are common in classrooms and studios. Storage in airtight containers helps prevent contamination and drying. It should be kept away from high heat to prevent decomposition or melt.

Historically, oil-based modelling clays date back to the early 20th century with products like Plasticine; plastilisel appears in some markets as a regional or alternative name for these non-drying clays. The term is not universally standardized and may be encountered mainly in art supply catalogs or regional discussions.
