I ended up getting this cast iron glue pot, it is a short story, but I am wondering about a heat source for it. How would a traditional woodworker have used this? It is like a double boiler configuration. I plan on getting the lighter strength hide glue from Lee Valley, more open time. My plans for the glue pot are to clean up the rust by scrubbing with steel wool and vinegar and then seasoning same as a pan but I am looking for more info on how to use it.
