plastilina

Plastilina, also known as plasticine or modeling clay, is a soft, malleable material used for sculpture, modeling, and education. It is designed to remain pliable and reusable, unlike many clays that harden after exposure to air or heat. This quality makes plastilina popular for prototyping, stop-motion animation, and children's crafts.

Most varieties are oil-based, containing waxes, mineral oil, petrolatum, and colorants. The base ingredients keep the material flexible at room temperature and prevent it from drying out. Because of its non-drying nature, plastilina can be reshaped indefinitely and mixed to produce new colors. There are variations in texture, from soft to firm grades, depending on the manufacturer and intended use.

It is often used for quick sketches of forms, maquettes, and character models, as well as for teaching and demonstrations. In animation, artists build scenes with plastilina figures and move them in tiny increments between frames.

Safety and care: Plastilina is usually marketed as non-toxic, but users should follow product labels. It may leave residues on fabric or skin and can stain porous surfaces; working on a covered surface and washing hands after use is advised.

Storage: Keep in airtight containers or wrap in plastic to slow drying; store away from heat and direct sun.

History: Plasticine was developed in the 1890s by William Harbutt in the United Kingdom, leading to the generic term plastilina in several languages.
