What is the standard interpretation of "Cynthia Bringle Slip"?
Recipe I've had:
Borax 25
Neph Syen 125
EPK 100
Ball clay 100
Silica 150
Bentonite 10
For white, use 7.5% superpax, zircopax, or tin oxide.
From Clayart's John Weber:
EPK 20
Ball clay 20
Nepheline syenite 25
Flint 30
Borax 5
Bentonite 4
Zircopax 15
