I have heard about pee drinking Health-Minded Germans...
A couple told me about it more than 10 years ago.

Drinking animal urine is (or was ?) practiced in parts of Arfica...
IIRC

Wanna see a picture?

Wow, just when you think you've heard it all...

.... you hear a bit more!

And taiwanese farmers eat cow poo with spoon when it is hot !!!!! And Kurdish people makes their homes from cow poo. I think they sleep windows open :) And Chinese farmers produces their natural gas for heating and cooking from their drops.

And the White House garden watered with sanitary waters and all the garden earth contained highest level of lead.

Haist reports that urine, wine and many other substances can be used to develop Silver Halide emulsions. I guess you have all missed these comments from past posts.

Lotsa photographic "emulsions" don't use silver: platinum.palladium,gold. Too slow for in-camera and more costly than silver.
Someone once posted a link,on this Forum, to an organization that collected fat from human lipo-suction and fed it to people in poor countries. It sure looked serious. But one never knows.

Also, Dose not the usefulness of pee as a developer depend on the pH of the individual's pee? I t can be acidic or alkaline, depending on one's diet.

Alkaline pee for developing, acidic pee as a stop bath?

So next time I produce a print that "looks like sh*t", maybe it's not all bad :)

That is for your customers to decide! :D
