(Skip to the * if you’re not interested as to why it is in a milk jug)
Here, there is an annual, weekend-long celebration that kicks off on a Friday night with an event called Luminaria. This is when the town’s residents light up the entire coastline with candles. For the last 3 years I’ve been
placing candles on a rock out in the water for fun, and to see if I can start a trend, eventually lighting up all the offshore rocks. These candles are noticed and enjoyed, then forgotten.
Next time, so folks remember (from the previous year) that they meant to participate in my rock lighting endeavor, I will light my candles days prior to Luminaria. Since many people only go to the beach on the weekends, even though they live nearby, it will have to burn for a full week prior, then ideally for the entire weekend, because I’m only swimming out there once. Er, make that twice.
The town agrees to clean up after this event because the candleholders (windbreakers) are made from recyclable plastic (mostly milk jugs). They have yet to retrieve the jugs I place on the rock, which is OK, I do. But so as not to undermine the environmental aspect of this event, thus alienating any would be helpers, I must continue using the 1-gallon jug (the largest town-recyclable container suited for this application).
* Someone would have asked. On to the idea…
A narrow candle would burn longer if it were wider, by having more fuel available. A wide candle will burn a hole through the center of the candle leaving unused fuel along the circumference. There is an optimal diameter, say 3 inches, where available fuel is maximized, and no fuel remains unused.
A 6” diameter candle will fit in a milk container to a height of 5”. At 5” it narrows due to a 1.5” indent for the handle on one side, and tapers inwards, but there is another 3” ‘usable’ height. ‘Usable’ because there must be enough space above the candle so the container doesn’t burn. This will be an unusually shaped candle – roughly 6” round x 5” high on the bottom, then a 6”x4.5” base off-centered by 1.5” tapering inwards to a height of 3” on the top.
A single wick will be used, because we’re going for duration here, and that wick must consume all of the fuel. To accomplish this, the wick will be spiraled through the candle. (Spiral wick candles exist, but with the wick on the outside of the candle.) Using the 6” x 5” bottom as an example: First, a stick of wax measuring 3” diameter x 5” high is molded. Wick is spiraled around the stick and held in place by painting melted wax on it. The stick is then centered in a 6” diameter mold. The result is 6” diameter candle with a 3” burn traveling in a 3” circle, thus consuming all 6” of wax.
The top portion uses the same technique, but includes some carving, unless you happen to have a mold that shape. The pieces are, of course, fused together, and the wick is contiguous. Cut a door in the container, insert the candle, seal the door, make a couple small air holes at the bottom and an angled rain deflector at the top. Ready to shine.
Note that this isn’t made of your ordinary paraffin or petroleum based waxes. It’s 100% pure, clean burning, long lasting cappings beeswax. I think it will burn for 3 weeks, but I have yet to find a reference by which to do the calculations.

This is just the first ref to gel "burn rate" I found... You'll have to dig for the rest (mind the dog(pile) poo!) - They seem to be in g/hr for the wicks... [Dub, Aug 24 2005]

It'll keep lots of bees buzzy (sorry) filling that little lot. Apparently Gel candals burn longer (ref. a candle book on Amazon ref from Google "cabdle maker" "burn rate" I think) |

Found a reference. <link> I estimate the volume of this candle at 206.17 cubic inches. At a burn rate of 15 hours per 4.51 cubic inches, this candle will burn for just over 4 weeks. That’s way longer than I need, and it should draw additional attention / curiosity just by staying lit that long. |

Got a link [Dub]? I’m all for trying other materials, provided they are eco-friendly, and I can work with them. |

Does having your wick at an angle, at whatever slope your helix would be, mean the flame can access the wick faster (the flame no longer has to descend straight down to reach more wick), and therefore burn faster? If this idea works, start making these right away. + |
|
| |
Amazingly wordy for a fully burning candle with a spiraling wick. But I'll give it a + anyway. |
|
| |
[Dub], there’s a few comparisons on those links, but no burn rates. |
|
| |
As I understand it, [sleeka], the wick is merely a conduit for drawing the wax to the flame, and barely burns itself except in the absence of wax. |
|
| |
//Amazingly wordy// I thought so too, but once it became some sort of geekish engineering challenge, I just couldn’t help myself. |

Candle companies will shun you now, since you basically made a perma-candle, making their high consumption-rate candles look foolish. I'm tempted to go build one to test it (using wax, though). Maybe you can get the burn time exact, so that each month can have its own candle (own color and scent), and burn out precisely at the end of that month - the Luminaria Calendar. |

this is all very lovely but I cannot help but wondering, doesn't the fecking thing get blown out? |
|

The container serves as a windbreaker. Most people cut a hole in the side and face the hole opposite the wind. Others cut the top off a 2-liter bottle and the flame burns well below the rim. These methods are OK, but out on the rocks the wind is stronger, so I cut a door to insert the candle through, then seal the door. This leaves the 1” spout (chimney, in this case) as the only opening. I think this opening may not allow enough air exchange to sustain the candle, so I make 2 small punctures near the bottom of the container. It’s very well sheltered. I haven’t had one blow out yet. |

[shz]Sorry, many of the links mention wick burn rate, and that Gel lasts longer, but you'll have to hunt through. There does seem to be a community though... there's bound to be FAQs and forums... Mostly to do with scented candles though. Trawl, and ask! |
|
| |
If you start at the bottom winding the wick in a helix you could burn the candle from both ends. |
|

Don't worry about the amazing wordiness, I enjoyed it. This is a top-notch idea, one of the best and most carefully formulated ones I've seen. Go for it. I'll buy loads. |

I'll let you know how it goes this summer. |

Nicely thought out [Shz]. [+] |
