I love tea. Especially at this time of year, when it is cold and dreary outside, a nice cuppa makes life so much better, instantly.
I also love to have the tea on a teapot-warmer - for some kinds of tea, especially black tea, this seems to keep the taste nice for a longer time, as opposed to putting the hot tea into a thermos bottle. (At least that's what it feels like for me.)
Teapot-warmers, though, need something to burn within them. Which, usually, means tea lights. Now, these come in handy little packages, each one in their little aluminum shell, and the wax is not the most eco-friendly stuff either. That always scratched on my green conscience.
So from time to time, I'd try different things. Beeswax tea lights. "Eco" tea lights with different wax. They all did not work properly, due to different reasons.
A while ago, though, I discovered an alternative and have now tested it for a bit: oil lights. They are basically a cork swimmer thingie, you insert a short little wick into that, fill something like a small, flat bowl with water, put some vegetable oil on top, place the wicked swimmer on it and light the wick. There you go. Small, lightweight, no aluminum waste, and just a bit of oil that hangs out in the kitchen anyways. Plus, the company that has been making these since 1867 is based here, in my region, and does all the production locally as well.
I would have linked to them here and now, but they do not sell to end-users, and the oil lights seem to be relatively hard to find. Which means... I am actually thinking about getting them into my shop. It has nothing to do with textile production per se, but it is a wonderful product, we all know textile people need hot tea (right?), and it might also be just the thing a few living history folks need. (There were hanging oil lamps in medieval times, which definitely need something to hold a wick. That would be another nice excuse...)
