You will need:
- A ball jar
- A wick material. Hemp cord from the hardware store works well. Try to get untreated hemp, cotton or linen. Make sure there is no plastic in your cord because it won't burn as well and it will release noxious gasses. A simple burn test may be performed: light the end on fire, if something in it melts rather than burns away, there's plastic present.
- a nut or washer to weight your cord so that it hangs straight down
- a pencil or another straight, stiff rod to hang your wick from
- melted, rendered lard
I waited another week before lighting the candle to allow the fat to penetrate the wick/cord. Alternately you may soak your cord in melted, rendered fat first.
