The flaming process for black granite

The flaming process for black granite involves exposing the stone to high temperatures (900°C to 1200°C), causing thermal shock that roughens the surface through exfoliation. This occurs because the minerals in granite, such as quartz and feldspar, expand at different rates under heat, leading to surface flaking. This process enhances the slip resistance of the granite, making it suitable for outdoor flooring and walkways while adding a natural, rustic aesthetic. Despite the rough texture, the granite remains durable, withstanding wear and maintaining its structural integrity. This technique leverages the principles of thermal expansion and mimics natural weathering processes.
