Abstract. Feldspar weathering occurs via dissolution of all components into solution, with the subsequent precipitation of secondary minerals from solution, and it is the feldspars dissolution rate which controls the overall rate of feldspar weathering.

Aug 10, 2019 · This mineral is often called potassium feldspar or K-feldspar because potassium always exceeds sodium in its formula. Potassium feldspar comes in three different crystal structures that depend on the temperature it formed at. Microcline is the stable form below about 400 C. Orthoclase and sanidine are stable above 500 C and 900 C, respectively.

Feldspar melts by itself to be a glaze, but crazes badly. Pure MinSpar feldspar fired at cone 6 on Plainsman M370 porcelain. Although it is melting, the crazing is extreme! And expected. Feldspars contain a high percentage of K 2 O and Na 2 O (KNaO), these two oxides have the highest thermal expansion of any other oxide.
