Description
Soda feldspar is a ceramic flux available in standard and washed grades, each suited to different tile and sanitaryware applications.
What it is
A sodium feldspar (albite, NaAlSi₃O₈) that acts as a ceramic flux, melting at a lower temperature than potash feldspar and giving faster vitrification.
Key applications
- Standard grade: used in general tile and sanitaryware bodies.
- Washed grade: iron and impurities removed for improved whiteness, used in premium tile and sanitaryware lines where high whiteness matters.
Choosing standard versus washed
Washed soda feldspar commands a premium over standard grade and is worth considering specifically for high-whiteness tile lines. Tell us which your formulation requires before requesting a quote.
FAQ
What’s the difference between soda feldspar and potash feldspar?
Soda feldspar melts at a lower temperature, giving faster vitrification. Potash feldspar vitrifies at a higher temperature. The choice depends on the firing profile and body formulation being used.
