I didn't know kids inherited the full content of their parents knowledge upon birth.
You love trying to leach your relatives for credibility when you know you have none of your own.
I didn't inherit anything. But I was her first born. I got taken to exhibits, had rock collections, knew Moh's Hardness scale when I was like six, the first book I really remember was my mother's old French's Engineering drawing.
Let's see, no Googling...
Talc Gypsum Calcite Fluorite Apatite Feldspar something something Corundum and Diamond. <--- M<oh's Hardness Scale back when I learned it.
Now via Google...
Mot bad. Orthoclase is new, back in the day it was Feldspar, which for all I know may BE Orthoclase.
