The creation of anthracite is the final product of the geological process known as coalification. Anthracite contains 90-95 percent carbon. While difficult to ignite, it burns longer and cleaner than any other type of coal (Wallace 1987). The anthracite coal region in Northeastern Pennsylvania contains most of the world's supply of anthracite.
