Does coal have a shine?
Yes, coal can have a shiny or lustrous appearance. It may exhibit a metallic or glassy sheen depending on its carbon content and composition.
Is Anthracite Coal opaque?
Yes, anthracite coal is opaque. It has a high carbon content and a black, shiny appearance that does not allow light to pass through it.
Which substance is called white coal?
i think its a diamond because it is also made of carbon atom and found in coal mines
Does coal have crystals?
Yes, coal can contain carbon crystals, which are known as macerals. These can give coal a glossy appearance and may be visible under a microscope. However, coal itself is not considered a crystal because it is an organic sedimentary rock made up of decomposed plant material.
Is coal dull or shiny?
Coal is generally dull in appearance, with a matte or non-reflective surface. It typically has a dark, black color and doesn't have a shiny or metallic lustre.

A metamorphic rock formed from coal?
Anthracite is a metamorphic rock formed from coal. Through heat and pressure, coal is transformed into anthracite, which is a hard, dark rock with high carbon content. It has a lustrous appearance and is often used as a fuel source.
What is luster of coal?
coal is non metalic because it does not shine like metal
What texture does coal have?
Coal has a smooth, hard texture with a shiny appearance. It is typically brittle and crumbly, though sometimes it can exhibit more compact, solid forms depending on its grade and level of compression.
What is the luster of coal?
The luster of coal is typically described as dull to sub-metallic. It does not have the shiny appearance of many minerals, as it is primarily composed of carbon and various other elements. Some types of coal, like anthracite, may exhibit a slightly more lustrous surface compared to others, but overall, coal's luster is generally not reflective.
How do you tell the difference between Obsidian rock and Coal Flint rock?
Obsidian is a natural volcanic glass that is typically black and glassy in appearance, whereas coal is a sedimentary rock that is typically black and dull in appearance. Flint is a hard, sedimentary rock that often has a dark grey or black color with a smooth or waxy texture, whereas coal is formed from plant matter and is combustible.
