Why is clay a good material for making pots?
As evaporation takes place the pots made up of clayey soil can keep the water cool inside. - Thus, the properties of clay minerals include capacity of the surface to take decoration, plasticity, colour after firing, fineness of grain, cohesion, hardness and the shrinkage under firing and air drying.
Clay has the ability to be molded into different sort of shapes and structures when water is mixed to it. After adding water to clay soil malleable material is formed. This is why clay soil is used for ceramics by ceramicists.
Clay pots retain Nutritive Value of Food
Clay pot's porous nature allows both steam and heat to circulate through the food, which results in thorough yet aromatic cooked food. This lets the food retain more nutritive value than food prepared in other kinds of utensils.
Pottery is made by forming a ceramic (often clay) body into objects of a desired shape and heating them to high temperatures (600–1600 °C) in a bonfire, pit or kiln and induces reactions that lead to permanent changes including increasing the strength and rigidity of the object.

Answer : (1) Clayey soil
This type ( Clayey Soil ) of used to make pots and toys.
Clay soils provide a wonderful foundation for plants by anchoring roots securely in the soil. Many perennials and annuals thrive in clay soils since they can get a firm grip on the soil with their roots. This firm grip allows them to survive extremes of temperature and moisture that plants grown in sandy soil cannot.
A major use of clay is as drilling mud—i.e., heavy suspension consisting of chemical additives and weighting materials, along with clays, employed in rotary drilling.
There are three essential properties that make clay different from dirt. These are plasticity, porosity, and the ability to vitrify. Plasticity has to be our first consideration.
The small size of the particles and their unique crystal structures give clay materials special properties. These properties include: cation exchange capabilities, plastic behaviour when wet, catalytic abilities, swelling behaviour, and low permeability.
What type of soil is good for making pots?
Clayey soil is used to make pots, toys and statues because the clayey soil has the highest water holding capacity than loamy, sandy and silt.
Plastic containers may be lighter and readily available, but they aren't environmentally friendly. Conversely, clay or natural terra cotta containers are made from a special soil that will eventually break back down into its original components should the pot break.
