Howdy all

I've been successful at baking & brewing, but
I still haven't figured out Pottery.

I buy the right block of clay, sketch and quality firing sheet
add water and nada. [These ingredients don't combine].

I've tried with both the firing sheet included and excluded
but neither has been successful.

I'm mostly stuck at the Pottery Wheel aspect.
What does one combine?

Thanks
