Sure, Babalu! Pass the mic!

Here is a small, but important thing to consider when designing a slip cast item. The bottom of most mugs, cups, vases, ect. are generally dished in like in this picture. The raised rim around the edge keeps the piece from rocking when sitting upright.

A separate mold part will need to be made to accommodate the undercut caused by the raised rim.

More on how this is done coming up!
