Eco-Smoking: A Unique Method of Brick Firing
Smoking is a special finishing process in brick production that gives bricks their characteristic darker tones and distinctive appearance. During this process, the hot bricks are exposed to a controlled kiln atmosphere, allowing subtle reactions at the surface of the brick that create rich, natural colour variations not achievable through firing alone.
Traditional Process
In conventional brick production, the firing and smoking stages take place separately.
Bricks are first fired at approximately 1100°C to achieve their strength and durability. After firing, the bricks are allowed to cool down. In a second production cycle, they are reheated to around 800°C, after which the smoking process takes place. Because these stages often occur in different locations, the bricks must be reheated and sometimes transported between facilities.
The Joseph Bricks Eco-Smoking Method
At our supplier Joseph Bricks, the firing and smoking processes are combined into a single, efficient production cycle. After the bricks are fired at 1100°C, they are cooled down to approximately 800°C, at which point the smoking process begins immediately.
By using the remaining heat from the firing stage, the bricks do not need to be reheated, which significantly reduces energy consumption. This innovative approach offers several environmental advantages:
Lower gas consumption
Reduced CO₂ emissions
Less transport between production stages
Reduced packaging requirements
The result is a more sustainable production process, while still delivering the unique colour depth and character that smoked bricks are known for.
