Trial and Revision

One of the designs we are working on is a cork lidded vessel. It's still very much in the trial and revision phase.  Working with two parts now, both the lid and mouth must align correctly. So the mouth must be very round to fit the cork lid just right. And the measurement of the vessel when wet has to be calculated, because as it dries and gets fired twice, the black mountain clay shrinks 12%.


Aaargh. Easier said than done!
