May 10, 2015 Weekly Weather and Mineral Guess

May 10, 2015

Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:

We have 10 individual guest minerals for the coming weeks.

The  Hardness  of a mineral defines how much it can resist scratching.
 
Hardness of 4 is our next guest. 
 
Our mineral guest this week is “F _ _ _ _ _ _ _ (also called fluorspar) is the mineral form of calcium fluoride, CaF2.”
 
F _ _ _ _ _ _ _ has ornamental and lapidary uses.  Industrially, F _ _ _ _ _ _ _ is used as a flux for smelting, and in the production of certain glasses and enamels.  The purest purest grades of
F _ _ _ _ _ _ _ are a source of fluoride for hydrofluoric acid manufacture, which is the intermediate source of most fluorine-containing fine chemicals.
F _ _ _ _ _ _ _ is used in microscopes and telescopes.
 
 

See below for discussion.

4.  FLUORITE

 

When I started this quest on mineral hardness, I though that I would list all 10 minerals with hardness from 1-Talc to 10-diamond.  As always, the devil is in the details.  With so many pretty pictures and so many industrial uses.  I thought that I would combine the two for each mineral.
Mohs hardness Mineral Chemical formula
1-Softest,Talc Mg3Si4O10(OH)2
2-Gypsum CaSO4·2H2O
3-Calcite CaCO3
4 Fluorite CaF2
5 Apatite Ca5(PO4)3(OH,Cl,F)
6 Orthoclase KAlSi3O8
7 Quartz SiO2
8 Topaz Al2SiO4(OH,F)2
9 Corundum Al2O3
10-Hardest. Diamond C
You can look up each mineral by Right Clicking with the Mouse on the Mineral Name.
….your fingernail has a hardness of 2.5,
….a penny has a hardness of about 3.5,
….glass and a steel nail have nearly equal hardnesses of 5.5 and
….a streak plate (tile) has a hardness of 6.5.
