1) Find some clay - on Freedom Deliverance, where you enter the world at Green Dog, the closest I have found is south of The Sanctuary. At the lake on the south border of The Sanctuary, on the far side of the land bridge (which is on the left/east side) is a deposit of both sand and clay.
2) Make a [[Clay jar]]. You might as well make a [[Clay bowl]] too. Activate your had hand as if it were a tool (double click on it - you can't be holding your sword or anything else). You will probably not be completely successful on the first try. This will result in an unfinished clay jar or bowl , and the icon is a darker grey than the clay icon. If you do succeed, the icon for the clay jar or bowl will be the same color as the clay icon.
2.1) If it is unfinished, you will need to finish it by applying the suggested tool (or water if that was suggested). Make the tool required (you probably won't have it - check [[clay shaper]] or [[spatula]]) if you need to.
