    For mixing chemicals from scratch I use small glass containers. I haven't heard anyone mention the static master brush in years. Didn't even know they were still made. I used one years ago for cleaning negatives before printing and I'm sure it would get rid of the static on your plastic containers as well.
    A little off topic but don't use an aluminum scoop for sodium hydroxide. I worked for a company that made chemicals for use in automated X-ray processors when I was much younger. The owner was a good chemist and all of the products were proprietary but we just couldn't get it through his head that aluminum and corrosives don't mix.:rolleyes:

    Drying. Friction will induce a static charge on any surface
    so inclined to generate a static charge. Plastics and glass
    surfaces are two. Static means just that, the charge does
    not flow. There is no grounding off a static charge.

    Dispelling the charge entails whole surface treatment.
    Ionization of the air is one way to drain away the
    electricity. Polonium will do that. Dan

    Au contraire, they mix very well. They become almost inseparable.

    Wow! I'm amazed at how much they can charge for a gas lighter! I got a handheld piezo electric one of those in a kitchen shop for a couple of quid a few years ago. But I used it to make a kirlian photography plate setup instead

    What other ways are there to ionize the air?

    I love my Staticmaster brush. I use it for photo films and also for chemical jars. any kind of powder which gets messy (and thus unclean/unsafe) because of static can be tamed with one of these brushes. Also, i use it on my scales to cancel out static charges. Get one. They are worth the price.

    stupid answer - with an air ionizer. They used to be quite popular for "clearing the air". Just basically electrical sparks at the end of the day, like a gas lighter, piezoelectric sparker whatever you want to call it.

    FD&C Blue #1. Ultrafine powder, very strong colour, gets everywhere, only usually spotted when it comes into contact with moisture and shows up very strongly.
    Although harmless, it also demonstrates why dust masks are a good idea. Bright blue bogies are not a reassuring look. :rolleyes:

    Yes, indeed!

    This can happen with photographic sensitizing dyes as well,
    which are perhaps not quite as harmless...

    When a small amount of moisture comes in contact with even an infinitesimally small amout of the dye... the dye becomes visible;

    the real fun begins when one "cleans" such an invisibly tainted surface,
    since it cannot be seen until you wipe over it with a damp cloth...
    dye suddenly "develops" out of nowhere and quite likely at the time, for no known reason!
