Description: Anthracite Coal Mineral Specimen Science Geology Home Schooling Anthracite coal is a compact variety of coal. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal.Peat, partially decomposed plant matter, is the first stage in the formation of coal. Lignite, the second stage, is formed when peat is subjected to increased pressure from accumulating sediments. Bituminous Coal is the third stage. Added pressure has made it compact and virtually all traces of plant life have disappeared. It is known as “soft coal”. Anthracite is the fourth stage in coal formation. Also known as “hard coal”, it formed as a result of combined pressure and high temperature. Anthracite is considered as a transition stage between bituminous coal and graphite. Graphite, under the right conditions, will turn into diamonds! This listing is for 5 pieces totaling 5.9 oz. anthracite coal specimen. The anthracite coal in the photos is the coal you will receive. All pieces have been washed but some crumbs/dust may result during the shipping process. If that happens, just rinse and dry and it will be clean to handle making it perfect for use as lumps of coal in a Christmas stocking!
