'''Coal''' is a black or brownish-black sedimentary rock, formed from dead plant matter which decayed and fossilized over millions of years, as the heat and pressure of deep burial converts the peat into coal.<br />
<br />
==Types==<br />
*''Anthracite'': the highest rank of coal is a harder, glossy black coal used primarily for residential and commercial space heating.<br />
*''Bituminous coal'': a dense sedimentary rock, usually black, but sometimes dark brown, often with well-defined bands of bright and dull material It is used primarily as fuel in steam-electric power generation and to make coke.<br />
*''Graphite'': an allotrope form of [[carbon]], difficult to ignite and thus not commonly used as fuel, instead it is used as lubricant or in pencils.<br />
*''Lignite'': also called ''brown coal, it is the lowest rank of coal, most harmful to health, used almost exclusively as fuel for electric power generation.<br />
*''Peat'': a precursor of coal, found in boglands.<br />
*''Sub-bituminous coal'': whose properties range between those of lignite and those of bituminous coal, is used primarily as fuel for steam-electric power generation.<br />
<br />
==Properties==<br />
Coal is a black or brownish solid material, insoluble in all solvents.<br />
<br />
Coal will burn at high temperature in the presence of air/oxygen<br />
<br />
==Availability==<br />
Coals are often sold in many hardware stores as fuel for ovens and other heating sources.<br />
<br />
Can be purchased online, from eBay, Amazon or Alibaba.<br />
<br />
==Projects==<br />
*Fuel<br />
*Metal smelting<br />
*[[Mineral collecting]]<br />
<br />
==Handling==<br />
===Safety===<br />
Mineral coal is harmful, as it contains various heavy metals and other harmful compounds.<br />
<br />
Coal ash, resulted from burning coal is toxic and harmful.<br />
<br />
===Storage===<br />
In closed bags, bottles or boxes.<br />
<br />
===Disposal===<br />
Best to take it to waste disposal centers if the wastes are too toxic.<br />
