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]
Plasticine is one type of clay used in claymation. 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 ...
Calcium reacts in the lime kiln with the clay minerals to produce silicates that enable some of the lime to set through hydration. Any unreacted calcium is slaked to calcium hydroxide which sets through carbonation. These are sometimes called 'semi-hydraulic lime' and include the classifications feebly and moderately hydraulic lime, NHL 2 and ...
The foam is created using a foaming agent, mixed with water and air from a generator. The foaming agent must be able to produce air bubbles with a high level of stability, resistant to the physical and chemical processes of mixing, placing, and hardening. Foamed concrete mixture may be poured or pumped into molds, or directly into structural ...
Re-wetting paper clay is faster with paper clay than pure clay, as the paper fibres pull water more quickly into the clay body. The damp sections can be then joined. Accelerated drying of paper clay work is possible, and results in less warping and cracking, compared with drying conventional clay.
Lime plaster is a type of plaster composed of sand, water, and lime, usually non-hydraulic hydrated lime (also known as slaked lime, high calcium lime or air lime). Ancient lime plaster often contained horse hair for reinforcement and pozzolan additives to reduce the working time.
