The materials required are few and simple. You'll need:
- a length of copper pipe
- two copper pipe caps to fit the pipe
- a length of cotton twine to serve as a wick (not some manner of nylon or poly, as those materials will not wick fuel to the flame and will simply melt and make a mess)
JB Weld will also do the job quite well. Soldering tends to leave scorch marks on your pipe, especially if you're an amateur like me, but a bit of sandpaper or buffing compound will polish things up nicely, if the shiny look matters to you.
|Note the hole in the center of the cap.|
The short version of my basic testing methodology was to look for anything marked "flammable" that was a liquid. These tests were just things I ran across in two small closets. Later testing with things in my garage will undoubtedly have interesting results.
For just a few dollars in parts and 15-30 minutes of time, candles like this are a great prep. They're durable and reusable, and not overly picky about what they eat. Polished up, they even make neat conversation pieces or gifts.
