Soda Feldspar Shortage

There is currently a shortage of Soda Feldspar in Australia because the importer – Sibelco – has run out of stock. We are endeavoring to source a suitable replacement but in the meantime are suggesting for standard simple gloss glazes a straight substitute with Nepheline Syenite or for more accuracy a blend of 78% Nepheline Syenite and 22% Silica.
