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 2 is our next guest.
It can be used as a fertilizer, is the main constituent in many forms of plaster and in blackboard chalk, and is widely mined.”  >  Sheet Rock.
What is it?   G _ _ _ _ _ .   Other varieties include satin spar, selenite, and alabaster.
 

See below for discussion.

Gypsumpsum

 

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.

Uses of gypsum

Gypsum is used in a wide variety of applications: Sheet Rock, gypsum blocks, gypsum mortar, plaster, fertilizer and soil conditioner, additive to tennis court clays, alabaster-sculpture, wood substitute, tofu, brewing, calligraphy, foot creams, shampoos, Chinese medicine, growing mushrooms, lead and arsenic removal, and etc.
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.
