Anthracite - an overview ScienceDirect Topics

Anthracite is a high-rank coal, representing a coal that has been subjected to the highest grade of metamorphism. Anthracite is shiny black, hard and brittle (see Figure 2.8) and has the highest fixed-carbon content (approximately 86–98%).Due to its low volatile matter (2–12%), anthracite's combustion process is slow. Most anthracites have low-moisture content (about 3–6%) and their ...

Mohs Hardness Scale: Testing the Resistance to Being

Mohs hardness picks: Hardness picks are easy to use. They have a brass stylus and an alloy "pick" that is used for hardness testing. Place the sharp point of a pick on your unknown specimen and drag it across the surface. It will either produce a scratch, slide across the surface, or leave a trace of metal. They are supplied with a hardness of 2 (a plastic point), 3 (a copper point), and 4 ...
