    Regarding the hide glue substitues made from potato flour, rice
    flour etc spoiling, You might try adding a drop or two of carbolic
    acid to the mix, and see if it acts as a preservative. I make batches
    of gum tragacanth, and just add some carbolic acid to it, and it
    seems to keep forever. 

    I used to be able to get carbolic acid at any hardware, feed store,
    or drug store, but the last time I went to get some I found I had to
    have a prescription. I haven't a clue as to why one needs a
    prescription now, but seems that in Oregon it is the law.
