C/4 Seger High Fire Glaze#14
Originally uploaded by claycraft.

Using the Seger analysis of Orton C/4 as a starting point, we designed

the following C/9 glaze base



KNaO .3 Al2O3 .5 SiO2 4.0

CaO .7



Then, we lowered the alumina portion to .300, and the silica portion to 3.0



KNaO .3 Al2O3 .3 SiO2 3.0

CaO .7



The base recipe is as follows :



Custer spar 59

Whiting 22

Silica 19

Total 100



It was colored using Cobalt Carbonate.



#60 = + 0.75% Cobalt Carbonate.
