At first I didn't like the pinholes.
This is a beautiful smooth glossy white glaze on any other ^10 clay, but on this red stoneware it pinholes. I assume the clay is releasing gas, but even with a 60 minute soak at top temp. it does not resolve the pinholes. I've learnt to like them now. Perhaps I will try a glaze with out whiting at some stage to see if I can help the glaze, but perhaps I'll just settle for this. It's not too bad.
