Now let it sit for a while until you get clay slabs, then break to collect clay:
Getting clay is not guaranteed. There is a higher chance you will fail and instead get mud, instead of clay. If you fail, then find another spot and start over:
The mud returns to dirt blocks after it rains, so that they can be useable once again. You do not mess with the muddy outlines or you will fail to get your clay 100%. Your only job is to mix with a stick and hope u find clay. Get curious and mess with the outline and it will break on you, only to start over.
So far this one pot after baking can be filled up with water and used for some of the mod's related things. More coming!
