antique cast iron cauldron pot, cute small size w/ handle to hang over rod

Early 1900s vintage glue pot or blacksmith forge crusible, very heavy cast iron, with a handle made to fit over a 1" rod or bar. This is cute, like a little witches cauldron!

The pot measures 5" in diameter across the rim and 4 1/4" deep. This has some surface rust inside and out, but looks good without any deposits.
