I’ve been searching for a glossy clear glaze to cover the sgraffito on my porcelain vases. These are my most recent results and I’m happy with them. The glaze recipe (which I found somewhere on the web) is:
ULATRA CLEAR GLAZE RECIPE cone 5/6 oxidation.
Minspar 200 (I substitued with F4): 8.6%
frit 3134 23.2
wollastonite 15.2
E.P.K 24.8
talc 4.3
Silica 325 23.8
