Plasticine is a putty-like modelling material made from calcium salts, petroleum jelly and aliphatic acids.

Because of its non-drying property, it is a material commonly chosen for stop motion animation, including several Academy Award-winning films by Nick Park.

Franz Kolb, owner of a pharmacy in Munich, Germany, invented an oil-based modelling clay in 1880.

Plasticine is approximately 65% bulking agent (principally gypsum), 10% petroleum jelly, 5% lime, 10% lanolin and 10% stearic acid.

In Spain, toy manufacturer Jovi markets a product also branded "Plastilina", made from vegetable matter which makes it lighter.

Harbutt patented a different formulation in 1915,[3] which added wool fibres to give plasticine a stronger composition intended for ear plugs, and as a sterile dressing for wounds and burns.

The use of a different chalk compound caused a product inconsistency, and the US version was considered inferior to the original mix.

Bluebird Toys plc acquired Plasticine through its purchase of Peter Pan Playthings Ltd, Harbutt's parent company.

One of its main proponents is Aardman Animations' Nick Park, who used characters modelled in Plasticine in his four Oscar-winning Wallace and Gromit short films A Grand Day Out (1989), The Wrong Trousers (1993), A Close Shave (1995) and A Matter of Loaf and Death (2008), as well as the feature films The Curse of the Were-Rabbit (2005) and Vengeance Most Fowl (2024).

If an athlete leaves a mark in the plasticine, it is considered proof that the jump was a foul, and the attempt is not measured.
