“The Strange Blowpipe 19th Century Miners Used to Analyze Ore” in WIRED
August 19, 2014 - Philadelphia, PA
Excerpted from an article by Greg Miller
Pretend for a minute that it’s 1875 and you’re a mining engineer whose job it is to figure out how much gold is in them thar hills. Get it wrong, and your company is going to waste a lot of time and money hunting for gold that’s not there—or worse yet, miss out on the mother lode.
Not to worry, though, you’ve totally got this. You grab your trusty blowpipe kit, much like the gorgeous set above, and get to work. . . .
That kit, as well as the older professional kit above, come from the collection of the Chemical Heritage Foundation museum in Philadelphia.
