Hi Loris
Isn't silver oxide the result of "detox'ing"  used fixer by dropping steel
wool in it?

Fascinating conversation... I'm going to have to try Agyrotypes
Thank You

Hi Don, I agree about kits (if you don't want to mess with chemistry), OTOH,
if one's going to get their hands dirty, compounding silver oxide from
silver nitrate + sodium hydroxide isn't that hard or fail-prone (just weight
the chemicals, prepare the solutions, mix them and then stir + decant 3-4
times...), and the cost difference would be significant in most parts of the
world.

Regards,
Loris.
