Paper clay is handmade or commercially available clay to which a small percentage of processed cellulose fiber is added. The fiber increases the tensile strength of the dry clay and enables dry-to-dry and wet-to-dry joins. Commercial paper clays air-dry to a firm, lightweight sculpture, with minimal shrinking during the drying process. [4]
An artist makes a negative plaster mold based on a clay positive prototype. 1–1¼" of the clay/water mixture is pressed into the mold. Wire mesh or other stiffeners are added to create the web, or clay body that surrounds the hollow cell. The product is air dried to allow the plaster to suck the moisture out of the green clay product.
Choqa Zanbil, a 13th-century BCE ziggurat in Iran, is similarly constructed from clay bricks combined with burnt bricks. [1] Mudbrick or mud-brick, also known as unfired brick, is an air-dried brick, made of a mixture of mud (containing loam, clay, sand and water) mixed with a binding material such as rice husks or straw. Mudbricks are known ...
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 ...
In preparing the clay, potters spend hours wedging it to remove air pockets and humidity that could easily cause it to explode during firing. The clay then needs to "cure" over time. [3] Coiling is the most common means of shaping ceramics in the Americas. In coiling, the clay is rolled into a long, thin strands that are coiled upon each other ...

The more fiber in the paper clay, the more rapid the drying with less warping and cracking, and the quicker dry-to-dry joins can be made. Nonconventional clay techniques are now possible after adding processed cellulose fiber to any clay: First, joining dry-to-dry paper clay and dry-to-soft paper clay are the most radical new techniques.
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]
