Which of the following are examples of clay ceramics?

Clay ceramics are materials made from clay that are hardened by heat. They exhibit properties such as durability, resistance to heat, and permeability, making them suitable for various applications.

Pottery is one of the most common forms of clay ceramics, used for making dishes, containers, and decorative items. Bricks are another exemplary clay ceramic product, utilized in construction due to their strength and thermal resistance. Both pottery and bricks are formed from clay that is shaped and fired at high temperatures, which transforms the clay into a hard, structured material.

The other options do not correctly represent clay ceramics. Glass and porcelain are different materials, with glass being an amorphous solid created from silica and other compounds, while porcelain is a specific type of clay ceramic that undergoes a particular firing process. Pottery and plasters include materials that are not exclusively clay ceramics; plaster, for instance, is made from gypsum rather than clay. Wood and metals are entirely distinct categories of materials and do not involve any ceramic properties.

Therefore, the correct choice reflects the traditional uses and forms of clay ceramics, highlighting both pottery and bricks as prime examples.
