Feldspar
Feldspar was a mineral. Along with diorite, it was one of the primary components of the mantle of Endor.[1]
The planet Guiteica held extensive underground reserves of this mineral. Many different pro-Imperial mining companies had tried to convince native Bitthævrians to perform mining activity on the planet.[2]
