The texture of coal is a 'hard, shiny, black rock.
However, the 'hardness' and the 'shininess' can vary depending on the impurities present. However, it is always black.
The texture of coal can vary from
Peat, )A black wet earth) coal in its early stages of formation. (Burns/combusts with a lot of smoke)
Then Lignite ; a soft black rock, with no wetness. ( burns/combusts with less smoke).
Then coal as described above ( burns/combusts with a hot bright flame, dependent on the amount of oxygen draught present).
Finally Anthracite ; hard and shiny ( Sometimes known as 'Black Diamond'( burns/combusts with a hot bright bluish flame, dependent on the amount of oxygen draught present).,
The texture of coal is fine-medium.
rough
Anthracite
Fine grain, rough and soft
Bituminous coal is described as:Diaphaneity (Transparency): OpaqueColour: BlackStreak: BlackCleavage: None ObservedSee PicturesIts texture is smooth, mostly glossy to somewhat dull, a soft coal. Once mined, it can easily break apart.Bituminous Coal exists in the geological area known as The Pittsburgh Coal Seam-- an area extending from Western Pennsylvania, Western West Virginia, Ohio, Kentucky, and Indiana. Though mined since the days of Native American Indians, and heavily mined since 1800, it is estimated there is still enough coal in this large seam to last millions of years.
what is aluminum texture
rough
Coal is fine grained, lack of visible texture.
Anthracite
Fine grain, rough and soft
Anthracite is a form of coal. It is hard black and shiny.

NO! it burns them to a black coal- like texture and look!
A folliated texture metamorphic rock, like shist.
The only ones i know are coal and chalk-Roselin R. PEACE!

Anthracite has a hard and compact texture. Its grain structure is fine-grained and dense, with a highly developed lamination and a bright, shiny appearance. It has a high carbon content and a low moisture and volatile matter content, making it a high-quality coal with excellent heat and energy properties.
