Cauldron ID?

[MartyG]

I've had this old cauldron for a number of years. Too bad it's cracked, but I paid next to nothing as I recall. It's approx 23" across at the top. No markings that I have found. Ay ideas who made these, or what they were used for, other than witches brew?

Maybe able to narrow down the search of use but not of maker.
