Clean Slate

This is a slate blue glaze on a red clay. The high iron content of the clay gave the glaze a greenish appearance where thin. Where thick it's a deep blue like the paint used on submarines. It's glassier than the original recipe description, which I'm thinking is because of a substitution of 3134 for 3124. It also might be because I'm using Unispar instead of Kona F-4. All in all I call this pot a success, it's got acceptable color response, and on the red clay the glaze stopped bubbling and healed over. I will probably reformulate this glaze with 3124 and apply it dipped on white clay in my next test.

This picture was taken with light from an open window. The sunlight brings out the green, inside the pot is blue.
