what is the shelf life of 250 bloom gelatin if cold stored?

[djkloss]

Found in my fridge a 1/2 gallon of 250 Bloom Gelatin from my last alt-process printing session - probably cyanotype. Any ideas on how long this stuff (working solution) lasts?

Thanks!

If it’s dry powder, pretty much indefinitely. If it’s already been melted into solution..until it starts growing mold / getting eaten by bacteria.

Thank you for responding Nodda Duma. I ended up throwing it out. It was too nasty looking and was easier to just make it fresh. Probably was a year old anyway.
