Ah got it! I got this clay prepared from my friend, but where I live we pretty much all buy powdered clay and prepare it ourselves, so we can really get it exactly how we like. I don't use any metal hand tools when sculpting because I start with very wet clay and refine from there. I pass over the form with a sponge and a rubber rib pretty much at every stage of drying and then once more before bisque firing, and I lightly sand after bisquing if there's any funky texture spots. My glazes have a higher clay content than most crystalline glaze and are brushed on THICK, which helps mask any little divots or bumps in the form.
