Shiny shady candle

For a shiny shady centrepiece

These beautiful candles are made in a variety of colours and patterns, from classic church white to rainbow striped. They are all "fat" candles, around two to three inches in diameter and about six inches tall.

Within the wax is a shiny metal cylinder just a few millimetres smaller than the candle so that it is unseen when the candle is new. Cut into the cylinder is a pattern of horizontal lines (see illustration), this will allow heat to be transferred from the wax inside the cylinder to the wax outside, while discouraging heat from being conducted downwards into the unburned candle.

As you burn down the candle the metal shade will gradually appear from within, making a nice shade from which beams of candlelight can emerge to dance upon your table.

(?) this idea seems like an inside out version of the stained glass effect candles. http://www.everythi...tml?GCID=C13230x015

Will conduct heat better horizontally than vertically. [wagster, Dec 01 2005]

       This would be a very pretty candle. Nice Idea!! [+]   

       The main problem with imbedding metal inside candles (I have found) is that as soon as it emerges near the flame it gets heated. Metal is an exellent conductor of heat and so the whole metal object heats up and melts itself free of the candle. I think that in its current form, the sides of the candle would quickly melt, leaving the metal piece loose and a pool of wax on your tablecloth...   

       This candle would be excellent if you found another material for your "chimney".

       Fiberglass mesh?
reensure, Dec 01 2005

       That is indeed a bit of a poser [Minimal]. I had considered the conductivity issue insomuch as wanting the metal to conduct heat to the outer few mm of wax so that it would melt away. Of course it would also conduct heat downwards, leading to structural wax problems.   

       I think I have the solution and will update the idea.

       It would be a shame to lose the shininess of your cylinder. Maybe you could coat it in a thin layer of transparent plastic to insulate it? I guess you would have to test it to ensure that the candle flame would not melt/ignite the plastic. Glass maybe?

       Ceramic sticks with bits of metal and glass linked between?
reensure, Dec 01 2005

       That would work, [wags]. My idea (incorparating [reensure]s good suggestion) is to glue many metal rings together into a vertical tube using a glue that would leave an insulation gap. After gluing you could still cut out the star-shaped windows. This would have the added benefit that you could snap off the upper rings when the chimney looked too tall.   

       Your idea has the benefit of being easier to manufacture, but would let the light peep out through the slots....

       Tagline: // Replace "light" with "sausages" and this may work... //   

       Alright: // As you burn down the candle the metal shade will gradually appear from within, making a nice shade from which beams of candlesausages can emerge to dance upon your table. //   

       About the actual idea: I think this could be more effectively done with just a metal plate with some holes in it that is embedded a few millimeters under the top surface of the candle, and moves down as the candle shortens. The holes are to allow molten wax to come up through it. It can have projections upward from its outer edge to serve as a shade (and keep all of the molten wax from pouring down the side).   

       It would work like the wick assembly in my idea [link] without the wick function.   

       I might bake my version of this; it sounds pretty easy.

       [notexactly] Which is going to heat first the plate contained wax or the wax with air boundary and a hot metal hat?
