Plasticine is a putty-like modelling material made from calcium salts, petroleum jelly and aliphatic acids. Though originally a brand name for the British version of the product, it is now applied generically in English as a product category to other formulations.
Plasticine is used for children's play and as a modelling medium for more formal or permanent structures. 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. [1] At the time, the city was a centre for the arts, and among Kolb's circle of friends were sculptors. They complained about how with the clay they were using for modelling, their sculptures would dry too fast and that, particularly in winter, it was too difficult to work with. In order to commercialize his invention, he presented it to the Faber-Castell company in 1887, which had back then the name "Kunst-Modellierthon" (known as Plastilin), where it is still sold nowadays under the name "Münchner Künstler Plastilin" (Munich artists' Plastilin). In Italy, the product Pongo is also marketed as "plastilina" and shares the main attributes of Plasticine.
Plasticine is approximately 65% bulking agent (principally gypsum), 10% petroleum jelly, 5% lime, 10% lanolin and 10% stearic acid. [2] It cannot be hardened by firing, melts when exposed to heat, and is flammable at higher temperatures.[ citation needed ] In France, it is made by Herbin, and marketed as Plastiline. In Spain, toy manufacturer Jovi markets a product also branded "Plastilina", made from vegetable matter which makes it lighter. Play-Doh, which is based on flour, salt and water, dries on exposure to air.
William Harbutt, an art teacher in Bath, England, formulated Plasticine in 1897. Harbutt wanted a non-drying clay for his sculpture students. He created a non-toxic, sterile, soft and malleable clay that did not dry when exposed to air.
Harbutt received a patent in 1899 and commercial production started at a factory in Bathampton in 1900. The original Plasticine was grey, but four colours were produced for initial sales to the public. Plasticine was used by children and was often bought by schools for teaching art. It has found a wide variety of other uses (for example moulding casts for plaster, and plastics).
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. [4] The Harbutt company marketed Plasticine as a children's toy by producing modelling kits based on characters from children's stories, such as Noddy, the Mr. Men and Paddington Bear.
The original Plasticine factory was destroyed by fire in 1963 and replaced by a modern building. The Harbutt company produced Plasticine in Bathampton until 1983, when production was moved to Thailand.
The Colorforms company was the major American licensee of Plasticine from 1979 until at least 1984. 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. In 1998, Mattel bought Bluebird and the brand was sold to Humbrol Ltd, known for its model paints and owner of the Airfix model kit brand. Flair Leisure licensed the brand from Humbrol in 2005 and relaunched Plasticine. It acquired the brand outright, when Humbrol entered administration a year later.
Plasticine and similar materials are used in clay animation. 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 film The Curse of the Were-Rabbit (2005). This technique, a form of stop-motion animation, is known as claymation in the US. Plasticine-like materials are appealing to animators because the material can be used with ease: it is mouldable enough to create a character, flexible enough to allow that character to move in many ways, and dense enough to retain its shape easily when combined with a wire armature, and does not melt under hot studio lighting.
Plasticine is used in long jump and triple jump competitions to help officials determine if the competitors are making legal jumps. A 10-centimetre-wide (3.9 in) 'indicator board' is placed beyond and slightly above the take-off line. The edges of this are chamfered and edged with plasticine. 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. [5] Plasticine is used rather than sand, so that several boards may be prepared in advance: if a board is marked it may be replaced by a smoothed board immediately to avoid delaying the competition, but keeping the marked board available in case of challenges. An indicator board is used, rather than a wide strip of plasticine, as this provides a firm footing should the athlete step on it.
Plasticine-like clays are also used in commercial party games such as Barbarossa.
Television presenter James May together with Chris Collins, Jane McAdam Freud, Julian Fullalove and around 2,000 members of the public created a show garden made entirely of Plasticine for the 2009 Chelsea Flower Show. Called "Paradise in Plasticine", it took 6 weeks and 2.6 tons of Plasticine in 24 colours to complete. May said, "This is, to our knowledge, the largest and most complex model of this type ever created." It couldn't be considered as part of the standard judging criteria as it contained no real plants, but was awarded an honorary gold award made from Plasticine. [6] [7] The garden won the Royal Horticultural Society's 'peoples choice' for best small garden. [8]
Plasticine is used by geologists studying rock deformation. One study compared the performance of four German products: Beck's green and Beck's orange made by Beck's Plastilin, Gomaringen; Kolb brown made by Kolb, Hengersberg; and Weible special soft made by Weible KG, Schorndorf. [9]
During World War II, Plasticine was used by bomb disposal officer Major John P. Hudson R.E. as part of the defuzing [10] process for the new German "Type Y" battery-powered bomb fuze. The "Type Y" fuze has an anti-disturbance device that had to be disabled before the fuze could be removed. [11] [12] [ unreliable source? ] Plasticine was used to build a dam around the head of the fuze to hold some liquid oxygen. The liquid oxygen cooled the battery down to a temperature at which it would no longer function; with the battery out of commission, the fuze could be removed safely. [13] [14]
Trinitrotoluene, more commonly known as TNT (and more specifically 2,4,6-trinitrotoluene, and by its preferred IUPAC name 2-methyl-1,3,5-trinitrobenzene), is a chemical compound with the formula C6H2(NO2)3CH3. TNT is occasionally used as a reagent in chemical synthesis, but it is best known as an explosive material with convenient handling properties. The explosive yield of TNT is considered to be the standard comparative convention of bombs and asteroid impacts. In chemistry, TNT is used to generate charge transfer salts.
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolinite, Al2Si2O5(OH)4). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide.
Silly Putty is a toy containing silicone polymers that have unusual physical properties. It can flow like a liquid, bounce and can be stretched or broken depending on the amount of physical stress to which it is subjected. It contains viscoelastic liquid silicones, a type of non-Newtonian fluid, which makes it act as a viscous liquid over a long period of time but as an elastic solid over a short time period. It was originally created during research into a potential rubber substitutes for use by the United States in World War II.
Enamel paint is paint that air-dries to a hard, usually glossy, finish, used for coating surfaces that are outdoors or otherwise subject to hard wear or variations in temperature; it should not be confused with decorated objects in "painted enamel", where vitreous enamel is applied with brushes and fired in a kiln. The name is something of a misnomer, as in reality most commercially available enamel paints are significantly softer than either vitreous enamel or stoved synthetic resins, and are totally different in composition; vitreous enamel is applied as a powder or paste and then fired at high temperature. There is no generally accepted definition or standard for use of the term "enamel paint", and not all enamel-type paints may use it.
Claymation, sometimes called clay animation or plasticine animation, is one of many forms of stop-motion animation. Each animated piece, either character or background, is "deformable"—made of a malleable substance, usually plasticine clay.
Polymer clay is a type of hardenable modeling clay based on the polymer polyvinyl chloride (PVC). It typically contains no clay minerals, but like mineral clay a liquid is added to dry particles until it achieves gel-like working properties. Similarly, the part is put into an oven to harden, hence its colloquial designation as clay. Polymer clay is generally used for making arts and craft items, and is also used in commercial applications to make decorative parts. Art made from polymer clay can now be found in major museums.
The Butterfly Bomb was a German 2-kilogram (4.4 lb) anti-personnel submunition used by the Luftwaffe during the Second World War. It was so named because the thin cylindrical metal outer shell which hinged open when the bomblet deployed gave it the superficial appearance of a large butterfly. The design was very distinctive and easy to recognise. SD 2 bomblets were not dropped individually, but were packed into containers holding between 6 and 108 submunitions e.g. the AB 23 SD 2 and AB 250-3 submunition dispensers. The SD 2 submunitions were released after the container was released from the aircraft and had burst open. Because SD 2s were always dropped in groups the discovery of one unexploded SD 2 was a reliable indication that others had been dropped nearby. This bomb type was one of the first cluster bombs ever used in combat and it proved to be a highly effective weapon. The bomb containers that carried the SD 2 bomblets and released them in the air were nicknamed the "Devil's Eggs" by Luftwaffe air and ground crew.
Harvie Krumpet is a 2003 Australian clay animation psychological comedy-drama short film written, directed and animated by Adam Elliot, and narrated by Geoffrey Rush. It tells the life story of Harvie Krumpet, a Polish-Australian man whose life is plagued by bad luck but who nevertheless remains optimistic.
Bathampton is a village and civil parish 2 miles (3 km) east of Bath, England on the south bank of the River Avon. The parish has a population of 1,603.
Sculpey is the brand name for a type of polymer clay that can be modeled and put into a conventional oven to harden, as opposed to typical modeling clays, which require a much hotter oven, such as a kiln. Until it is baked, Sculpey has a consistency somewhat like Plasticine. Its main competitor is the German brand Fimo. It is sold in many colors, but can also be painted once it’s baked. Sculpey has become popular with modeling artists, jewellery makers, and other craft work.
William Harbutt was an English artist and the inventor of Plasticine.
Modelling clay or modelling compound is any of a group of malleable substances used in building and sculpting. The material compositions and production processes vary considerably.
Danger UXB is a 1979 British ITV television series set during the Second World War. It was developed by John Hawkesworth and starred Anthony Andrews as Lieutenant Brian Ash, an officer in the Royal Engineers (RE).
Object animation is a form of stop motion animation that involves the animated movements of any non-drawn objects such as toys, blocks, dolls, and similar items which are not fully malleable, as plasticine (clay) or wax are, and not designed to look like recognizable human or animal characters.
Sewage sludge treatment describes the processes used to manage and dispose of sewage sludge produced during sewage treatment. Sludge treatment is focused on reducing sludge weight and volume to reduce transportation and disposal costs, and on reducing potential health risks of disposal options. Water removal is the primary means of weight and volume reduction, while pathogen destruction is frequently accomplished through heating during thermophilic digestion, composting, or incineration. The choice of a sludge treatment method depends on the volume of sludge generated, and comparison of treatment costs required for available disposal options. Air-drying and composting may be attractive to rural communities, while limited land availability may make aerobic digestion and mechanical dewatering preferable for cities, and economies of scale may encourage energy recovery alternatives in metropolitan areas.
Colorforms is a creative toy named for the simple shapes and forms cut from colored vinyl sheeting that cling to a smooth backing surface without adhesives. These pieces are used to create picture graphics and designs, which can then be changed countless times by repositioning the removable color forms. The name also refers to the specific registered trademark brand these products are produced under, as well as the company that manufactures the toys, Colorforms Brand, LLC.
Humbrol Limited is a British brand and former manufacturer of paints, solvents, and other accessories for scale model kits and toys. In the past, Humbrol produced under its own brand and the Airfix, Sky Marks, Young Scientist, 1st Gear, High Speed and W. Britain brands.

Resin casting is a method of plastic casting where a mold is filled with a liquid synthetic resin, which then hardens. It is primarily used for small-scale production like industrial prototypes and dentistry. It can be done by amateur hobbyists with little initial investment, and is used in the production of collectible toys, models and figures, as well as small-scale jewellery production.
Events in 1897 in animation.
The "/Y" fuse behaved exactly like the normal one when tested, but it had an additional circuit that was isolated after activation. This circuit contained mercury tilt switches which would detonate the bomb if the fuse were turned, even slowly. This was a booby trap designed to kill bomb disposal personnel
It was believed that by using liquid oxygen poured over the fuze head the necessary very low temperature within the fuze could be achieved.
That was wonderful when we got a bomb with the fuze lying at the top but if the fuze was at the side, it wasn't quite so easy. [...] I think it must have been me who thought of the idea of making a little neck of clay around the side to hold the liquid. I think I used plasticine actually.
