Recipe:
31 Frit 3124 used local high Boron Frit
23.2 Wollastonite
31.7 Kaloin EPK
14.1 Silica
ADD
3.5 Copper Carb.
5.5 Rutile
Note: All raw materials are measured up or down to the nearest half
decimal. Colorants or additives to a 100 gram batch are measured in percent
to the 100 gram batch.
Results:
Gloss, light green glaze, with movement and streaking on surface. Pinkish
cast where streaking separates overall green ground. Where glaze moves and
collects at bottom of dipping edge, glaze is raised but not dripping. My
frit has made this glaze glossy, could add some EPK in further testing.
