JohnnieV---- Are you using a clay that fires black? Or is that a surface treatment (slip, glaze, stain, whatever)?
I would be very careful about that stuff. Ask someone the chemistry behind that black clay. I myself would hesitate throw with a clay which has elevated levels og Manganese, cobalt or any other metal besides iron.

If it is a reduction firing, it may not be safe to eat from.

However, those bowls in the other threads looked awesome! Keep up the good work.

(sorry, MM. I addressed the wrong person originally)
