My local studio only sells cone 5 clays, and I want to fire in my home kiln to cone 6 because glaze results are usually better. I have two clays that say to never fire over cone 5 because of bloating: Speckled B-mix and B3, so I won't do those over 5...but the other clays I have don't say NOT to fire over cone 5....I have Laguna's Dover White that just says its a cone 5 clay (but doesn't say not to fire over cone 5)...so I'm wondering if it might be ok to ^6? Anyone have experience with this one? I also have Some Aardvark clays like Sedona Red & Bmix 5, that on their chart is under the cone 5/6 category, which is confusing to me because it's name has a 5 in it, does that mean I can't fire that to ^6 either? Thanks!
