OK, for those who’ve been following my thread in the ATMB forum, here is a copy of the e-mail I sent TubaDiva:
So there you have it. I have no idea how much to offer as a reward, partially because I have no idea just how much expense obtaining such a lamp might involve. For starters, let’s say $20 or 20% of the lamp’s cost, with haggling allowed.
What you want is called an Argand lamp. This one is a bit pricey, but it’s a genuine antique and absolutely beautiful. I suspect that, knowing what it’s called, you can likely find a modern reproduction that’s somewhat more affordable.
Unfortunately, a genuine period antique is beyond my price range; if anyone makes modern duplicates of those, the example you linked to would be great.
Lehman’s has a small collection of “olive oil lamps”, which will burn any vegetable oil. They don’t look like they would be as efficient as some of the antique lamps in the other links, especially without any kind of reflector to concentrate the light.
I’ll keep looking through those from time to time, but apparently virtually all such lamps were electrified and no longer can burn oil; or they are “student lamps” in style but have always been kerosene burners.
Cut a round hole in the skin of the tangerine in the bottom. This will officially be the top. To determine hole size, imagine you are working on a tiny jack-o-lantern.
Extract the orange segments* but leave that pulpy stem thing attached inside. This is your lamp’s wick.
Pour in two or three tablespoons of vegetable oil and let set a bit. Then light your wick and you have a cute little lamp. It smells good too!
*You get bonus fun points if you can get all the segments out without damaging them. It is possible if you’re careful.
Meant to add for Lumpy, I’m wondering what if you just bought a wick that can be used with vegetable oil and put it in a lamp of your choosing? This site says some of their fiberglass wicks can be used with biofuels. They might have other alternatives but I don’t have time now to look. Hope this might be of some help though.
