Uranium nitrate toned silver prints aren't stable from what I've heard, and
have seen them bronze out.  I still have prints that have not bronzed or
changed much by my eye.
If you can find uranium nitrate, formed as a by-product of testing uranium
which is done by pouring nitric acid on it, then you can easily make the
toner w/ferricyanide and acetic acid.
