The earliest cast iron artifacts, found in China, date back to 513 BC. The Chinese of this time had developed furnaces hot enough to melt iron. Using this process, they were able to pour molten iron into a cast or mold to make many products, including cast iron cookware. In 1708 Abraham Darby invented a process for making cast iron in large industrial quantities, suitable for making big structures such as bridges, heavy machinery, etc. His invention helped to start the Industrial Revolution in Europe.
