- An active
flux, increasing the fluidity of a melt.
- Has highest
coefficient of expansion therefore decreases the tensile strength
and elasticity of the glaze and can increase the potential for

with Na2O and expressed as KNO or KNa2O in unity formulae calculations.
- Similar to

(especially soda feldspars) for high temperature glazes.
- Fritts -
usually used in low temperature glazes.
(not commonly used due to fluorine volatility).
