I have only worked with earthenwares, stonewares and raku clay. But I'd like to make something that fires smooth and creamy for a change. Would that be a porcelain clay? If so, can anyone suggest a porcelain clay (cone6) that handles somewhat like any of the above? I have the impression that porcelain is muuuuch more difficult, but I'm hoping that I'm wrong about that. Is porcelain a completely different animal or does it handle pretty much like other clays?
