You have probably heard the saying…”Shino first or suffer the curse.” This saying pertains to mixing shino with other glazes when glazing a single piece. It is common wisdom to apply shinos first as they tend to be highly viscous, by their nature, and will allow the often less viscous overglaze to melt and flow well. The other way around and there will be a high price paid for not heeding the shino first warning.
I , by nature, don’t follow rules too well, particularly those that pertain to art. I began experimenting with applying various shino types glazes over less viscous glazes, like tenmoku, chun reds, celadons and slips. By all that I’ve been told I would surely suffer “…the curse.” Turns out the old saying is not true, in fact the results were quite amazing and interesting, IMO.
I encourage some experimentation by breaking the rules.
The three yunomi in the image above were first glazed with Alberta Slip and let dry about half way, they were then glazed with CT Shino and left to dry over night. The cracking will begin to appear about 18-24 hours after glazing. If the cracking does not appear, the efforts in the following images will not be achieved. I’ve found that the cracking works best with the base glaze being applied on the thicker side. Notice the brownish crystals on the surface of the glaze, this is the soda ash migrating to the surface that aids in carbon trapping.
The image above is the fired result of CT Shino over Alberta Slip. Fired to ∆10 in reduction with an early reduction starting at 1560F.
