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]
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]

Chamber drying provides a means of overcoming the limitations imposed by erratic weather conditions. With kiln drying, as is the case with air drying, unsaturated air is used as the drying medium. Almost all commercial timbers of the world are dried in industrial kilns. A comparison of air drying, conventional kiln and solar drying is given below:
African red slip ware: moulded Mithras slaying the bull, 400 ± 50 AD.. A slip is a clay slurry used to produce pottery and other ceramic wares. [1] Liquified clay, in which there is no fixed ratio of water and clay, is called slip or clay slurry which is used either for joining leather-hard (semi-hardened) clay body (pieces of pottery) together by slipcasting with mould, glazing or decorating ...
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 .
Clay was chosen due to the local material being easy to work with and widely available. [26] Scribes wrote on the tablets by inscribing them with a script known as cuneiform, using a blunt reed called a stylus, which effectively produced the wedge shaped markings of their writing. After being written on, clay tablets could be reworked into ...
