Robert ... I have been trying to figure your cracking problem. It is so odd that a slip cast mug would consistently crack. You mentioned that you thought the nose was too long. Is it possible that the mold could have a place (like in the nose) that forms in such a way that a void is created? Also is the plaster you use of really good quality? Perhaps there are some impurities in it that cause the greenware to dry irregularly. That may lead to week spots. Because of that, the mold may be the problem. Also, have you tried to fire them using a simple glaze (like a clear) to see if they crack? An old glaze may have gone out of solution and not be firing on evenly applying uneven pressure as it cools. I'm racking my brain .... sorry if I seem to be shooting in the dark.

So glad the barrels came out ... cool stuff .... Gene
