Clinker bricks are called "clinker bricks" because of the metallic sound, or "clink," they make when struck together.
Clinker bricks are a unique type of brick produced when standard bricks are over-fired during the manufacturing process. This excessive heat causes the bricks to vitrify, resulting in a dense, hard, and often misshapen product. The process alters the brick's structure, making it much more durable and resistant to water damage. Consequently, clinker bricks have a distinctive appearance that includes a blackened or heavily textured surface.
Characteristics of Clinker Bricks:
Here's a breakdown of the characteristics of clinker bricks:
- Appearance: Typically dark, often blackened, and sometimes with a glazed or melted appearance. They often exhibit irregularities and imperfections.
- Density and Weight: Significantly denser and heavier than regular bricks due to the vitrification process.
- Sound: The "clink" sound produced when struck against each other is a defining characteristic.
- Durability: Exceptionally durable and resistant to weathering and water damage.
- Shape: Often misshapen, warped, or split due to the intense heat they are subjected to.
Summary
In essence, the name "clinker brick" directly relates to the distinctive ringing sound they produce. This sound is a result of the vitrification process that makes them a durable and unique building material.
