Clay enables plants and animals to stand.

Plants and animals that can stand are made of clay as follows:

1. Knead the clay into 1 big 6 small balls.

2. Make six balls into the shape of flowers.

3. Put the big ball on it.

4. Then take a little clay, knead it into a flat shape, find a suitable tool and poke a hole in the middle.

5. Then decorate the side of the big ball.

6. Finally, decorate small eyes on both sides, and a clay sculpture octopus is ready.

Composition of clay:

Clay is generally formed by weathering silicate minerals on the earth's surface. It is an important mineral raw material. It consists of various hydrated silicates and a certain amount of alumina, alkali metal oxides and alkaline earth metal oxides, and contains impurities such as feldspar, mica, sulfate, sulfide and carbonate.

The particles of clay minerals are fine, often in the range of colloid size, crystalline or amorphous, most of them are flaky, and a few are tubular and rod-shaped. Clay minerals are plastic when wetted by water, can be deformed under small pressure and can remain unchanged for a long time, and have large specific surface area and negatively charged particles, so they have good physical adsorption and surface chemical activity, and have the ability to exchange with other cations.

Clay is mixed with proper amount of water to form a mud mass. Under the action of external force, the mud mass deforms but does not crack. After the external force is dispersed, it can still maintain its original shape. This property of clay is called plasticity.
