Plastocene
Plasticine is a putty-like modelling material made from calcium salts, petroleum jelly and fatty acid, aliphatic acids. Though originally a brand name for the British version of the product, it is now applied Generic trademark, 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 Awards, Academy Award-winning films by Nick Park. History Franz Kolb, owner of a pharmacy in Munich, Germany, invented an oil-based modelling clay in 1880. 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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Modelling Clay
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. Ceramic clay Ceramic clays are water-based substances made from clay minerals and other raw materials. They are baked at high temperatures in a process known as firing to create ceramics, such as terra cotta, earthenware, stoneware, and porcelain. Paper clay produced by pottery clay manufacturers is a clay body to which a small percentage of processed cellulose fiber has been added. When kiln-fired, the paper burns out, leaving the clay body. Consequently, the firing temperatures and glazes selection should be the same on those used with the clay body. Oil-based clay Oil-based clays are made from combinations of oils, waxes, and clay minerals. Unlike water, the oils do not evaporate and oil-based clays remain malleable even when left in dry environments for long periods. Articles made f ...
