Being a bit of a mad scientist, I saw some beads (that's right -beads)
that proported to change color from silver to gold in sunlight. They
do - and the reaction takes place in seconds, not minutes, leading me
to think that a silver salt is involved. But, its not permanent - they
revert to silver within about 10 minutes under artificial light - and
can't be fixed by water or hypo. It may be that the chemical, whatever
it is, is under a clear coating.
But its a very pretty gold tone, and would make nice photo prints if I
knew what it was. Also, I'd then be able to know how to fix the image.
ANybody have an idea??
