Tuesday 20th January 2015

Pinholing is often related to the smoothness of the underlying body surface. The lower half of this vase was tooled during the leather hard stage, all the pinholes occur there. Even though this glaze contains 10% grog, the pinholes are not appearing on the upper half because the slip generated during throwing has left a smooth surface.
