I used to make three aluminum foil balls the size of golf balls, then flatten them with my palm. Put them on a flat dish. Light a small stump of candle and leak wax in the middle of the dish to stick the base of the candle to, then get a clay (terracotta) flower pot, turn it upside down over the candle percher on the foil balls. Wait a few minutes, and it became a nice hand warmer, and put out hot heat. Learned that as a kid when on my uncle’s tug boat.
