    Okay... Show of hands... How many of us remember a high school or college chemistry teacher who drank his coffee out of a Pyrex beaker?

    Or, better yet, how many of us have been chemistry teachers who drank their coffee from Pyrex beakers?

    This is a supremely unwise idea.

    Do not use any cooking utensil for holding photochemicals either. Do not use a cooking pot or measuring cup for chemistry that might ever be used for food!

    All my photo stuff that is food-like (e.g. pitchers) are marked "Not for food/Photo only" with a sharpie.

    I don't want them recycled and somehow end up in someone else's kitchen someday. I don't want to ever ask myself, "is this one that I used for photo?" (even though I don't use anything similar in my kitchen for just this reason).

    it is OK to say that photochemistry is harmful to one's health ??

    too funny

    I don't know what your point it. That conversation was pretty clearly tending towards respect for photo chemicals.

    This conversation is trending the same way.

    You can put your popcorn away.

    We drank from pyrex beakers sometimes even at EK. But, we had dedicated coffee beakers and dedicated chemistry beakers. The company even supplied us with food and chemical refrigerators, and no food was allowed in labs, just office areas. Refrigerators for chemicals were modified for use with chemicals, as the auto defrost equipment could actually start a fire or cause an explosion. And, to prove it, they demonstrated how by blowing the door off a commercial refrigerator in the middle of a field.

    So, don't store solvents or chemicals in a food fridge.

    Yes, my teacher's "coffee mug" rarely varied off the path between his desk and the teacher's lounge but, even if it did, it never went as far as the lab.

    I often use empty food containers like snap-top margarine tubs and plastic milk jugs in the darkroom because they are free and plentiful. I can use them a couple-few times and, when they get icky, I can throw them into the recycle bin. There are always new ones to take their place.

    These containers are always labeled with their contents but, most importantly, the path from kitchen to darkroom to recycle bin is always a one way street.

    Nowadays, if you blew the door off a fridge, you could easily get 1,000,000 hits on YouTube!

    Oooh, good point.
    WYSIWYG - At least that's my goal.

    Most labs in the microbiology field just throw away lab glassware after one use. It is much easier and way less expensive than designing and documenting and implementing cleaning procedures that will keep the FDA satisfied. I'm fairly sure beer is acidic and silver is soluble in acids, so . . . . . . . . . . . . . . . . .

    I can't even get the tomato sauce smell out of a plastic bottle that had tomato sauce in it, despite soaking and washing numerous times.
