The first variation of this glaze was produced in 1975-76.  It contained far less soda ash and also was based on a single particle size of nepheline syenite.  The balance between F-4 feldspar and nepheline syenite was also favoring more F-4 feldspar.  

 

The addition of the redart clay causes the glaze to take on a more peachy tone overall.  It can be omitted and the EPK content upped by the 1% amount for a whiter result.
