C/4 Seger High Fire Glaze#8
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 .400
KNaO .3 Al2O3 .4 SiO2 4.0
CaO .7
The base recipe is as follows :
Custer spar 46
Whiting 18
EPK 7
Silica 24
Total 100
It was colored by equal amounts of Cobalt Carbonate and
Green Chromium Oxide.
#54 = 1.5 Cobalt Carbonate and 1.5 Green Chromium Oxide.
