Dear Brian Guffey,=20
Interesting to know that these felspars, which both contain K2O and =
Na2O, are Cone 10 fluxes. Yet you suggest Neph Sy which is a K2O-Na2O =
mineral.
I think Barry asked about getting rid of the out gassing from a sample =
glaze which had already fused well at cone 8 and which was suffering =
from blisters and pits. I cannot for the life of me see how changing =
melting fluxes will accomplish his objective.
Perhaps you could explain.
Best regards,
Ivor Lewis
