I am making signs from rolled slabs for gifts. I have success with them, but they warp slightly in the glaze fire. They are not warped after bisque. Can you tell me why and what I can do to prevent it? I am using a low fire red clay with a significant amount of grog. Glazing is underglaze and clear glaze on top.
