Judy SA Posted Monday at 05:17 AM Report Share Posted Monday at 05:17 AM I have a round nickle bank mold that every time I pour it, it caves in (does not stay attached ) to the mold. The mold is very dry. What can I do to correct this? Quote Link to comment Share on other sites More sharing options...
Chilly Posted Monday at 03:42 PM Report Share Posted Monday at 03:42 PM (edited) Try pouring the slip out more slowly. If it fills the pouring hole, it will cause a vacuum and pull the lining with it. There was similar questions asked before, with other suggestions. I'll see if I can find them.

Jeff Longtin Posted Monday at 06:55 PM Report Share Posted Monday at 06:55 PM An alternative solution: if thinning the slip doesn't help you might consider making the pour hole larger OR adding a second pour hole altogether. Years ago I made a mold of a Vanhool bus model. (I also made the model.) The mold was about 22" long and 8" square. I put one pour hole, at each end, to prevent a vacuum. Wouldn't you know the customer emptied it sideways and created a vacuum. When they called to complain I explained that the two pour holes were intended to prevent such a thing. They changed their method and all was well. Quote Link to comment Share on other sites More sharing options...
