Have you seen a situation like this before? Sure, it is very convenient, and cheap, to store lab chemicals in food containers. But it's not cool. For one, the turpentine in that coffee can isn't much use now that the volatiles have all evaporated out. Then, what the hell is the white powder all over the mayo jar of xylene? I don't think it is mayo. I think this kind of storage is against the law, though I can't find a reference immediately, but it certainly violates both recommended practice (see NIOSH/CDC guide) and common sense.
The Grolsch bottle in the background full of acetone reminds me of a story from a few years back, a friend was working on his boat, and pouring waste epoxy into a nearby empty beer bottle. A few minutes later, when reaching for his bottle full of beer, he grabbed the one with epoxy in it. One short trip to the emergency room later and a cheap and handy way to dispose of a chemical becomes neither cheap or handy. A final example before I go. One prolific collector that I know loves to store thick solution adhesives (i.e. Vinac B-15) in little Visine eyewash bottles. Well, sure, they work well for dispensing adhesive cleanly and one drop at a time. But in the field, have you ever gotten dust or dirt in your eye, and wished for eyewash? Does a foreign object in the eye blur your vision? Might you consolidate your eye closed? So much for getting the red out.
Be Cool. Only store chemicals in properly labeled containers not intended for food use.
Matthew Brown works in a slightly obscure corner of paleontology doing work called fossil preparation. Fossil preparators spend most of their time actually doing what most people think all paleontologists do all day. He has worked for the University of Chicago, Field Museum of Natural History, the National Park Service at Petrified Forest, and currently the University of Texas at Austin. Now residing in Swinging South Austin, he recently lived off the grid in a dome in the middle of the Painted Desert, where his cat Jake was eaten by a bobcat, coyote, mountain lion, or phytosaur. Gustav, Jake's replacement, fared pretty well, and stayed behind in Arizona to guard the house.
