offcntrIt's been a while since I've added any new glossary terms, so here's one:
Pin-holing. A glaze defect leaving small pits, sometimes sharp-edged, in the glaze surface. In stiffer glazes, like my white base, this can be caused by small irregularities in the clay underneath, if the glaze doesn't flow to fill them. In other glazes, particularly those with a high titanium content (Woo's Blue, for instance), pinholes form when gas bubbles burst from the molten glaze but don't smooth over again. These guys can be very sharp-edged.
