I made a face jug and I'm worried that there may be parts of it that are too thick and may explode in the kiln. It's a very nice piece so I really want to avoid that. It's almost 1 1/2 inch and my teacher has always told me to never fire a piece past 1 inch, but she's been wrong before. Is this a safe thickness to fire?
P.S. It's lowfire clay if that helps any. ~Thanks
