Bad Bowls

I was pretty happy with the insides of these bowls until I looked more closely. The glaze shivered where the drips were fairly big. These are a thin line of Wood Ash near the rim over Bone Ash (double runny) - a combo I've used many times but not on this clay body (New cone 10 Birch from Mile Hi). The funny thing is that one of the bowls crackled on the walls and shivered at the bottom.
