Articles relating to modelling clay, any of a group of malleable substances used in building and sculpting. The material compositions and production processes vary considerably. The material compositions and production processes vary considerably.
Modeling requires a malleable or plastic material which is later cured or fired to set it hard. Typical modeling materials include clay, wax, plaster, and papier-mâché. Frequently the modeling material has limited structural strength and will need the support of an armature.
Polymer clay is a modelling material that cures when heated from 129 to 135 °C (265 to 275 °F) for 15 minutes per 6 millimetres (1 ⁄ 4 in) of thickness, and does not significantly shrink or change shape during the process. Despite being called "clay", it generally contains no clay minerals.
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. [1]
The pointing machine is used for making one-to-one copies of existing sculptures and to reproduce models made of plaster, modeling clay or modeling wax in materials like stone or wood. It is not possible to use a pointing machine to produce enlarged or reduced copies; the traditional instruments for this are a set of calipers or a three ...
A modern drawing of a clay vessel unearthed in Vinča, found at a depth of 8.5 m (28 ft) The Vinča symbols [a] are a set of undeciphered symbols found on artifacts from the Neolithic Vinča culture and other "Old European" cultures of Central and Southeast Europe. [3] [4] They have sometimes been described as an example of proto-writing. [5]
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.
Industrial plasticine, or "clay", which is used for this purpose, is a malleable material that can be easily shaped, thus enabling designers to create models to visualize a product. Clay modeling was soon adopted throughout the industry and remains in use today. [citation needed]
