ANTIQUE JAPANESE EDO/MEIJI ERA 1800's BRONZE OIL LAMP & OIL POT with WARMING TRAY

  

One of the pots would have contained oil and a wick that was lit like a candle. The other small kettle would have contained extra oil and both are contained in a tray to avoid tripping.

The ray may have also been filled with hot water to keep the oil liquid.
