That's strange. But is the 'reaction' which causes the bitter taste from some random component of the tobacco or the nicotine itself? Elsewise, of
course, e-cigs wouldn't help in detection. Though somehow smoking a giant cigar sounds more cool than an e-cig in the lab anyways, even though e-cigs
look postmodern/steampunk.

I usually try to keep food away, but I drink coffee in the lab all the time.

I frequently drink and smoke in my lab/shed
but most of my chemicals are at least food grade

Yeah, I drink water and milk in the lab, but usually finish before I actually start something or just drink it while I watch something, not while I'm
working. I don't like to taste the vapors or powders which have drifted into my drink and dissolved, as I usually am able to taste that sort of
thing...

Overstocking due to odd availibilities - Started in my first lab a decade ago with 1lb of NH4I (Malinkrodt!) for $25, learned a lot about how NOT to
prepare elemental iodine - Now the remaining ~100g is used in mg amounts as a substitute for catalytic I2 in a handful of reactions. I've got a few
more examples, especially when it comes to pyrotechnic chems, but that's one of the gems in the collection.
And then theres just about everything regarding improper handling of glassware - Karma's a bitch - Over the span of a week not long ago I lost
probably $300 in beakers and 24/40 gear in the wash sink.
Biggest one though is not respecting heat, and the last lesson is gonna stick with me for a while. I was attempting to prepare toluenesulphonic acid
ala Norris, but using an oil bath rather than steam. After six hours or so I was getting impatient, and decided to toss in a stirbar to get things
moving - Well, move they did, in the form of a geiser of hot acid directly into my face. Thankfully, I wear glasses, and had a 5lb box of baking soda
in reach - scrubbed down, jumped in the shower, and began the long and not-fun healing process.
. . . Got damn lucky but a few scars are still gonna be there for a long while - Lesson learned - Let it cool before introducing nucleation points!
In the back of my mind I knew this, but that "done this a thousand times" mentality is occasionally difficult to overcome.
If you see me running, try to keep up.

Not washing my glassware after an experiment. It may not seem like a big deal, but it's a real pain to clean it later.

with just about every professional chemist using glassware

Story of my chemical life right there...
Also, I always dry things on a hotplate, just because I'm in a hurry. Usually end up splattering stuff everywhere...

Me too. I've had to resort to piranha a couple of times. Quality of glass is a factor too. I notice Kontes sep funnels and flasks come clean in soapy
water even after sitting around for weeks. Chemglass not so much. Bomar gets etched easily. Pyrex is as good as kontes. Wheaton makes good soft glass.
Seems like you can beat a wheaton container with a hammer and not break it. And they are in the US! Vineland NJ at last call. As an aside, I recommend
Scientific Machine and Supply of Plainfield, NJ for threaded glass couplings. The owners were lens makers and still affiliated with a lens
manufacturing plant. They cut the threads on a machine lathe. These hold vacuums well. I used to work for them designing glassware. We didn't make the
glassware there but had a shop in Vineland do the donkey work. They also make ptfe replacement parts and sleeves. I'm looking for a good glassblower
in PDX if anyone knows or has a favorite. Ahhh - too many topics!!!

Quite cool that you used to work at such a place. I have noticed my few Pyrex pieces come clean a lot easier than the china-glass, but also that they
look cleaner to start out with, have more of a sparkle to them.
