This is an update to my previous Olive Oil Lamp post. On your left you will see a simple photograph (webcam) of me holding one of my DIY olive oil glass jar lamps. :=D Daddy is so proud!
Basically, I use a rather wide thick-glass jar, cut some white cotton sock for a wick, and bend some steel wire to hold that wick in place above the oil. Beautiful. Utsukushii. I have this smaller one for my room - a lovely hand warmer and atmosphere setter, and another bigger one for my outdoors camp. The lid is used to kill the flame, while it also keeps the smoke inside as it dies.
