Today, concrete block manufacturing is a highly automated process that can produce up to 2,000 blocks per hour. The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6

The final step in graphite manufacture is a conversion of baked carbon to graphite, called graphitising, i.e. heat-treating the material at temperatures in the region of 2600°C 3300°C. During the graphitising process, the more or less pre-ordered carbon (turbostratic carbon) is converted into a three-dimensionally ordered graphite structure.
