Chapter 426 - 426 425 Black Fire Brick
?Chapter 426: Chapter 425: Black Fire Brick Chapter 426: Chapter 425: Black Fire Brick After deciding to hire Crooked Hat William to teach in the yet-to-be-established technical school, Lord Russell, accompanied by William and his son, inspected the Blackfire Brick Kiln.
The Black Oil furnaces were already operating, with no standardized equipment customization. These Black Oil furnaces were designed based on the masters’ experience, but the results were quite impressive, with the output being no worse than coal.
Slag bricks could now be mass-produced and were being transported continuously to the construction site of the new castle.
“Sir, look,” William pointed to the smoking chimney. The chimney was thick, surrounded by a ring of stair scaffolding, “This chimney not only expels smoke but also air-dries the clay bricks using the black smoke produced by burning Black Oil.”
William proudly said, “It was our workers who figured this out. The smoke from the Black Oil contains magic power, which makes the slag bricks stronger and more resilient, impervious to being smashed.”
Pausing, he continued, “Because there’s not enough clay slag, the production of slag bricks is intermittent, so we produce more of these ordinary bricks… After being air-dried by the magic power in the black smoke, these ordinary bricks also become stronger, only their color has turned from red to black.”
Rows of black bricks were neatly stacked on the ground.
Lord Russell picked one up and roughly felt it, indeed finding it to be more resilient than ordinary bricks.
It was not that the hardness had increased, but the resilience had.
Ordinary brick was fragile and easily broken, but this black brick, imbued with a certain substance from the black smoke, had become extraordinarily resilient.
