Coal – Anthracite
£1.00 – £1.90
Anthracite coal specimens, a vitreous, high grade coal with a hard and compact nature, these samples are from the Carboniferous coalfields of South Wales, UK and are one of the coals which have fewer impurities and a high carbon contents. Available in optional sizes, each sample will come supplied in a card tray with a label.
Anthracite (Greek ἀνθρακίτης (anthrakítes), "coal-like", is a hard, compact coal with a vitreous luster. It has the highest carbon content, the fewest impurities, and the highest calorific content of all the coal types. It is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 92.1% and 98%. It accounts for around 1% of global coal deposits. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. Anthracite is categorized into standard grade, which is used mainly in power generation, and high grade (HG) and ultra high grade (UHG), used principally in the metallurgy industry. These examples are from the Carboniferous coalfields in South Wales, specimens are supplied in labelled card trays and are available in various sizes.
