Interesting piece here! I have no idea were the red come from! There is red iron oxide decoration on the shino, which could be a factor. Potters say “Shino first or pots be cursed,” which means if your using shino to glaze make sure you apply it first and anything else goes on top. however, i use oxide washes over shino all the time, and never had a problem. oh well! Its a mystery!
