Which of the following are examples of clay ceramics?

The correct answer focuses on the materials that are classified as clay ceramics, which are primarily composed of clay and are typically formed by shaping and then firing at high temperatures. Clay ceramics are known for their durability, thermal stability, and aesthetic qualities.

In this context, pottery and bricks are both made from clay and undergo a similar process of shaping and firing. Pottery is often used for functional and decorative items, while bricks serve as a fundamental building material. Both represent traditional applications of clay ceramics, showcasing their versatility in various forms.

The other choices include materials that do not fit the definition of clay ceramics. Glass is not a ceramic; it is an entirely different type of material, typically made from silica. Concrete is also not classified as a ceramic, as it is a composite material primarily made of cement and aggregates, not clay.

Ceramic tiles and glass pottery, as found in another option, include a mix of ceramics and glass but do not strictly pertain to clay ceramics because the glass component deviates from the clay-based classification. Thus, pottery and bricks stand out as the clear examples of clay ceramics.
