In the 16th century stamps (dropping pestles) began to be used to pulverize ore. Machine pulverization began to develop in the second half of the 19th century. The principle of operation of the ball mill, the basic pulverizing device, was already known 150 years earlier; the prototype of the modern mill was invented in the 1870's.
A number of technological advances made the industrial revolution possible. In 1709 Abraham Darby (1677-1717), who owned an ironworks, began using coke instead of charcoal to melt iron ore.
