Feldspar Soda
Soda Feldspar is generally a clean white mineral that sources sodium, alumina and silica along with some potassium and calcium. In many cases, soda and potash feldspar are interchangeable in glaze recipes. However, some differences will be apparent. Soda Feldspar normally melts better. Also, slightly different colour responses will be encountered (i.e. cobalt tends toward purple copper toward blue with Soda Spar). Sometimes colours will be brighter with soda feldspar. In addition, soda spar has a higher coefficient of expansion and melts earlier and has a shorter range before it begins to volatilize
