Hi - I am using porcelain for the first time, and while I knew it was persnickety, I am having an unexpected problem: it keeps breaking while I'm glazing. While one pot was a very thin (too thin probably) vase, I have had multiple cup handles break in the middle or away from their attachment site. The handles were not pulled - they were coils that I smoothed with a sponge, so I wondered if maybe the clay was not compressed enough? The handles were relatively small but the cup was small and thin, too, so I don't think that is the problem. It is a cone 10 Narra porcelain, and they were bisqued to cone 06. They seemed very stone-like and sturdy, no visible cracks, so the breaks were a big surprise. I'm getting really frustrated...any ideas would be greatly appreciated! Thanks, Anita
