How much clay do I need?

[ant550lag]

Hi,

I am building a clay dome oven, and the diameter of the oven will be 90cm. What weight of clay would I need? I am using a clay that is specifically for pizza ovens, so I believe it already has the sand added, so I won't be mixing it with sand.

Thanks!

The usual mix is 1 part clay to 2 parts sand by volume. A higher proportion of clay will lead to excessive shrinkage forming cracks.
