This is something that surprisingly works great.
Make a tripod to hang your small cooking pots from that is measured to where the pot is within about a half inch of the top of the lamp. This will ensure that the heat from the lit lamp will go right to the pot. You can easily make one out of wood - making 3 legs and a wooden center to put the hook on for hanging the pot.
You can quickly boil water, make coffee, warm up canned food, etc. Great way to have warm food when you have no power. You can find these lamps at thrift stores and yard sales all of the time. Great investment. I think , right now, that I have 12 of them! I buy them when ever I see them. LOL I am a kerosene lamp hoarder and I am not embarrassed by it. You can never have enough.
