Formula: CaO.Al2O3.4SiO2 or CaAl2Si2O8
Alternate Names: Lime Spar, Lime Feldspar, Ca-Feldspar

DENS - Density (Specific Gravity)
HMOH - Hardness (Moh)
GSPT - Frit Softening Point
Feldspars are roughly divided into lithium, potash, soda, and calcium according the to fluxing oxide that predominates (theoretical formulae for each type are not found in nature). Calcium feldspars are not common and never near theoretical. Thus even if the CaO does not predominate over the K2O and Na2O it may still be labeled a Ca-Feldspar if there is an appreciable amount.
