I am testing some Laguna Cone 10 B-Mix. Would someone be willing to share a
clear glaze recipe which they have found has good =22fit=22 on this clay at =
Cone 10?
I'd like to use the recipe as a basis for getting the expansion value right,=
or
pretty close, early in this testing process. Thanks in advance for any =
help=21

0.054 Na2O 0.005 Fe2O3 0.005 TiO2=A0
0.815 CaO=A0 9.9:1 Si:Al Ratio
0.005 MgO=A0
Percentage Analysis:
72.20 =25 SiO2
12.40 =25 Al2O3
2.95 =25 K2O
0.82 =25 Na2O
11.31 =25 CaO
