Just one thought/observation though. From what i can see, and i could be wrong, but you didn't account for the thickness of the clay. The 'outside' of the clay that is touching the concave shape you made is going to have the same radius, but the 'inside', what is going up against the glass, is going to have a slightly smaller radius because you're building from the outside in. It might not be much, and your 6.5% allowance might make up for that after its shrunk and been fired, but if i'm correct with what i'm thinking, you'll have to add enough extra foam to the glass to make up the thickness of your clay before you make that fibreglass thingy.
