anyone have a good patching mix for bisque? Thinking of trying to use paper clay as the patch material but the body is regular clay.
Yes. For small batches, soak toilet paper over night, squeeze dry, put it into a blender, add powdered clay body to be repaired, Use about 25% paper to clay
about add some vinegar, and a smaller amount of sodium silicate
Blend into a paste. Ad a little water if you need to.
Dampen the bisque well before applying or else the patch will peel away.
Re-bisque before glazing. I have repaired students' handles and some of my own architectural work using this.
