Once the maize cultivation became more prevalent, the mano became a larger, two-handed tool that more efficiently ground food against an evolved basin or trough metate. [4] Besides food, Manos and metates were used to separate and pulverize clay from earthen debris and stones. The resulting clay was used for pottery-making. [5]
There are also several traditional techniques of handbuilding, such as pinching, soft slab, hard slab, and coil construction. Other techniques involve threading animal or artificial wool fiber through paperclay slip, to build up layers of material. The result can be wrapped over forms or cut, dried and later joined with liquid and soft paperclay.
A pot-in-pot refrigerator, clay pot cooler [1] or zeer (Arabic: زير) is an evaporative cooling refrigeration device which does not use electricity. It uses a porous outer clay pot (lined with wet sand) containing an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed. The evaporation of the ...
The method, a form of passive controlled-atmosphere storage, works by sealing fruit in the clay-rich mud, restricting flow of air, moisture and microbes, much as a plastic bag would. Discs are formed from two bowl-shaped pieces, which are sculpted from mud and straw, and baked in the sun before being filled with up to 1–2 kilograms (2.2–4.4 ...
Hand-building: This is the earliest forming method. Wares can be constructed by hand from coils of clay, combining flat slabs of clay, or pinching solid balls of clay or some combination of these. Parts of hand-built vessels are often joined with the aid of slip. Some studio potters find hand-building more conducive for one-of-a-kind works of art.
They are made by the combination of two types of clay: the first is taken from the surface of the earth and the second after digging more than 10 feet deeper into the earth. Making a matka is a long process of at least 8 days. The clay is mixed with water, shaped, finished, polished, dried and fired in a kiln for 5 days.

They are commonly durable buildings built from timber, stone or clay used to safely store valuable commodities. Kura in rural communities are normally of simpler construction and used for storing grain or rice. Those in towns are more elaborate, with a structural timber frame covered in a fireproof, clay outer coating.
