Anyone have a Shino formula that is known to work well on bone dry wares?
I am hoping to avoid bisque firing but I guess I will if I have to .
I have some of this Gustin shino made up ... (not sure if Chris actually had anything to do with it )
:
Could this maybe be tweaked to work on bone dry with the addition of bentonite ?
Gustin Shino
Nepheline syenite-45%
F-4 Soda feldspar-10.8%
Spodumene-15.2%
OM # 4 ball clay-15.0%
EPK-10.0
Soda ash-4.0%
Perhaps bisque fire is the best option no matter what if the wares are already bone dry ?
Thanks in advance for any advice on this !

Tim,
Maybe if you used calcined kaolin for all of the ball clay. Still iffy though. Test.
