It sure looks like a fire starter missing the wand to me. The pots were filled with oil, kerosene, etc. and the wand, which had a porous stone on one end, sat in the pot soaking up the starting liquid. You pulled the starter wand out let it drip for a few seconds, lit it and then used it to start your fire. A container of sand was kept nearby to extinguish the starter once the fire was going and you can find these with grains of sand in the bottom.
