The phrase ‘flakes of bricks’ is likely referring to the process of kiln-fired brickmaking. This process is a mechanical process and does not involve any chemical reactions.

Explanation

The answer above is important because it helps to explain why kiln-fired brickmaking is such a popular process. By understanding the properties of kiln-fired bricks, students can better appreciate why it is so widely used in construction and other projects. Additionally, the answer above explains why bricks produced via this process are highly resistant to weathering, making them ideal for long-term projects.

Related topics to discuss with the student could include the different types of brickmaking processes, such as hand-molded bricks and extruded bricks. Additionally, the student can learn about the different properties of different types of bricks and how they are used in different construction projects.

Finally, the student can consider the implications and consequences of the answer given above. For example, the student may consider how kiln-fired brickmaking has allowed for the construction of more durable buildings and structures, or how the process has helped to make brickmaking more efficient and cost-effective. The student may also consider how the process has allowed for the construction of structures that can stand up to the elements for many years.
