BlowpipesThese are very similar to what early chemists and mineralogists used for blow pipe analysis of minerals. Consult a suitable text (Brush & Penfield, O.C. Smith, etc.) for details of how this procedure was done.
Even the Chemcraft manuals detailed some experiments with the blowpipe. Fifty or sixty years ago, before instrumental analysis became commonplace, the old-time technique was discussed in nearly every chemistry and mineralogy text. It is still a useful part of learning mineralogy, and also for amateur prospecting.

Please be sure to wear safety goggles and gloves when using the blowpipe.
Never inhale when you have your mouth to the blowpipe and the other end up to a flame! You must use the nose to breathe in, using the blowpipe only for exhalation. Otherwise you could inhale poisonous and/or hot gases.
It is recommended to use a small, low-powered air pump (e.g., an aquarium pump) to provide air for the blowpipe, rather than using your mouth.
Also please remember that this item is made of metal; it can therefore become hot (to use it properly, you don't actually need to touch the flame with it).
