Hello Folks. It has been far too long since I've been active and posting anything on CCS, but during my too-frequent eBay searches during pandemic lockdown, I came across something that had been on my radar for years, but I never actually expected to find. I thought it would be worthwhile putting in the "other countries" gallery, as, even though it came from England, I am unsure of the maker, or actual country of origin. This stove is generally referred to as a "Russian Spirit Lamp", and usually was featured as a source of heat for laboratory applications. However, numerous mid-19th century sources clearly indicate that the Russian spirit lamp was also used for camping and the like, including in Edward Whymper's The Ascent of the Matterhorn, where it is featured prominently in the preface. My example is fairly small, but made of quite thick brass, with a turned brass lower potion, making it quite heavy. It would have originally been equipped with a small lid or cover, which also doubled as a measure for the alcohol. One measure would be poured into the ring-shaped outer chamber through the fill tube running through the handle. This tube was then closed with a cork (which formed a natural pressure relief valve!) A similar measure of alcohol was then poured in the bottom of the main chamber and lighted. The flame would heat the alcohol in the outer chamber, vaporizing it, and forcing it with some pressure through the jet. This would apparently result in quite a powerful upward blast of flame, suitable for heating water quickly, or carrying out any operation that needed short duration, intense heat. I have drawn a rather poor cutaway diagram which should clear up my equally poor description. In any case, the principle is quite simple, and very similar to the well-known alcohol burning "Eolipyle" type blowlamp, only vertically oriented. So there you have it, an interesting, early form of portable liquid-fueled pressure stove that had some popularity for outdoor cooking before the Primus style stove took the world by storm! Would love to know if anyone else has one of these, as this is the first I have seen in person. Cheers, Doug E.
