I know everyone is familiar with Candle Lanterns: http://candlelantern.com/ My wife and I have a few of the triple candle models that we use during the summer on the patio and at our picnic table.
The replacement candles are about 1" in diameter X 3-1/2" long and according to the package are formulated from special wax with a high melting point and use a special wick. I must admit, they do burn clean, do not seem to drip and do seem to last for the 9-hours as advertised. They also cost about $0.70 each.
I figure that I can use PVC pipe or conduit as a mould and make my own candles for maybe $0.10 each. The craft store sells several type of wax and wicks.
If anyone has made their own Candle Lantern candles, what kind of wax did you use? What size wick? Will something like Pam work as a mould release agent?
