If you have a mold line that is difficult to remove from a piece of greenware, dampen the piece slightly. It will come off easier and lessen the chance of breakage
If the thickness of your slip is about 3/16” in the mold, it is about ready to be drained unless you want a particularly thick piece.
After draining a mold, be sure to set it back upright to prevent the formation of nipples or lumps on the bottom surface.
Heavy seams in greenware can be the result of not banding your molds tightly enough.
If pieces collapse when removed from the mold, try putting a foam rubber piece inside of the greenware and nesting them in shredded paper to dry.
Cracks around the pour hole of a greenware piece are commonly caused by tearing, rather than cutting, the spare off and may only appear after firing.
