Steam engines had been too powerful for leather-based bellows, so forged iron blowing cylinders had been developed in 1768. Steam powered blast furnaces achieved higher temperatures, permitting using more lime in iron blast furnace feed. (Lime rich slag was not free-flowing at the previously used temperatures.) With a sufficient lime ratio, sulfur from coal or coke gasoline reacts with the slag so that the sulfur doesn’t contaminate the iron. As a end result, iron production rose considerably Technology News over the last decades of the 18th century. Coal transformed to coke fueled larger temperature blast furnaces and produced forged iron in much bigger quantities than before, permitting the creation of a variety of buildings such as The Iron Bridge. Cheap coal meant that business was now not constrained by water assets driving the mills, though it continued as a priceless supply of power.
