Feldspar - Wikipedia

Dec 22, 2009· The presence of potash feldspar in a glaze or clay body has a more refractory effect on the ceramic surface compared to equivalent amounts of soda feldspar. Although potash feldspar actually begins its melt at a lower temperature than soda feldspar, once the melt begins, the formation of leucite crystals causes a slower and more viscous flow.
