Coal Minecraft Wiki

Coal is a mineral item mainly obtained from coal ore. It is primarily used for crafting torches and campfires, as well as fuel. Coal ore are mined using a pickaxe and drops 1 piece of coal. If the pickaxe is enchanted with Fortune, it may drop an extra piece per level of Fortune, up to a maximum of 4 with Fortune III. Wither skeletons have a 1⁄3 chance of dropping a single coal upon death ...

Mesh and Micron Sizes Chart | ISM Industrial Spec

A 100mesh screen has 100 openings per inch, and so on. As the number indicating the mesh size increases, the size of the openings and thus the size of particles captured by the screen decreases. Higher mesh numbers = smaller particle sizes. It is very important to remember that mesh size is not a precise measurement of the mesh opening size.
