    I remember in the 70's era biology class in Jr high we routinely handled formaldehyde with no safety precautions mentioned period.

    Ahh, yes, the eternal Frog dissection class!

    Ours went over a 2 week holiday and the Frogs were beginning to ripen when we got back, even in spite of the Formalin and the cooler chest.

    Must be a fairly common US public school experience.

    I can remember vividly the experience complete with classmates huffing the jars of formaldehyde haha.
    This was in 7th grade down here in MD.

    Bet this doesn't happen today.

    Oh my I remember that stuff from my muscle car model building days.
    I also remember when it started disappearing from stock due to paranoia from someone.

    edit: oh btw I meant I bet they don't dissect anything these days due to political correctness etc

    I have no idea. I preferred Botany, it was not as messy and smelly. But, if you take Biochemistry then you have to "sacrifice" your own test animals for enzyme extraction or organ / tissue examination. My good friend Marge used to tell us how many pigeons she offed in a day! Meanwhile, in another building I was merely making Phenidone type compounds by mixing and boiling! I had the easy less messy job.

    Alternative to Formalin

    Can Zinc Acetate be used instead of formalin? It also is an anti-fungal and is mentioned in Grant Haist's book.

    No. The Formalin reacts with the couplers. Zinc Acetate does not.
