cheers for that..............to be quite honest it works and throws a nice ammont of light......far more so than a candle...............it is 3/4 's full of parafeen and sits on the desk and no longer smells...but is always ready to be lit ....as we have several power cuts here from time to time......
i have been looking at some of the large drawing room oil lamps on the net ...some of them with glass shades.....i bet they threw some light as well...
