In 1828, James Beaumont Neilson patented the hot blast iron smelting process, which revolutionized the iron industry during the Industrial Revolution. This innovation allowed for the preheating of air before it entered the furnace, significantly increasing the efficiency and output of iron production. As a result, the cost of iron decreased, facilitating its widespread use in construction and manufacturing, which was crucial for the rapid industrial growth of the time.

The innovation of hot blast iron smelting in 1828 catalyzed the growth of industrial poetry, where poets like William Blake lamented the 'dark satanic mills' and critiqued the environmental and social consequences of rapid industrialization. This industrial backdrop inspired a new wave of poets to address the human condition amidst the mechanization of life.
