When my crock pot cracked, I could not send my lid or bottom to the dump. Instead I took the solid glass lid and added it to my vegetable garden for a frog pool. I simply turned it upside down and buried the handle until it was flat to the surface of the garden. I filled it with water and hope to see a few frogs.
As for the ceramic base, I think it would make a nice flower pot for one of the flower beds. It has a crack in the bottom and would drain nicely if I set it up on natural rocks.
