Links to Other Materials
Miscellaneous
- Family: Feldspar
- Region: None
- Mined At: Unspecified
- Raw Mineral: No
- Generic: Yes
Notes
Feldspars are roughly divided into lithium, potash, soda, and calcium. Theoretical formulae for each are generally not found in nature. Almost all feldspars will contain some CaO, Na2O, and K2O at least.
If possible it is best to enter the analysis of the exact feldspar brand used and employ it in recipe calculations.
