    Antacid tablets and B&W developer chemistry

    I was about to pop a couple Miralac antacid tablets when I noticed the active ingredient is Calcium Carbonate (420mg). Just below that, it says "with Glycine and mint flavor".

    I'm at work and my mind started to wonder...I wonder if these would make a good developer???

    What do you think? Would it work?

    Glycine and glycin are two different chemicals.

    Glycine is an amino acid harmless to people and found in foods.

    Glycin is a developing agent. If you swallowed some, you would probably never have to worry about developing film again, sadly.

    Hmmm, doesn't sound too promising. So much for day-dreaming. Back to pounding out code!

    Yes, the Glycin and Glycine names are unfortunate.
    Calcium carbonate is also not a suitable alkaline materials for making developers (it's not water-soluble!)

    Acetaminophen, the active ingredient in Tylenol, is a derivative of paraminophenol (think Rodinal) and can be used as a developer. There was an article some years ago in one of the photo magazines describing how to use it. You might do a web search for more information.

    That's very interesting. I don't remember which movie it was, but I always think of those vietnam war photojournalist who (well in the movies anyway) wandered far from civilization and "made do" with whatever materials and makeshift equipment they could find. I often wonder if this is how they discoverd that instant coffee can be used to dev film.

    Tylenol eh? who would have guessed? At least it has some use. Sure doesn't work on headaches.

    Coffee contains several compounds which are substituted catechols. If I remember rightly this was the tipoff since catechol is a developer.

    There were two articles in the old Dignan Newsletter. One described the use of Tylenol and the other how to use a hair dye kit as a developer. One set of capsules in the kit contained paraphenylenediamine which is a fine grain developer.

    Are you sure that movie was Vietnam and not Cambodia? What's that movie where the journalists are hold up in the embassy and try to make a fake American passport to get their local assistant out?
