About two years ago I came across a sealed bottle of Rodinal that I
purchased in 1967. Gave it a try .... it was just fine. No "rocks."
A few years ago, I was handed an unopened bottle of HC:110 that had to be 20
years old.
Sadly, it had yellowed from oxidization through the plastic, but it was
still potent.
Rodinal should last pretty much forever in a new sealed bottle.
I expect the rocks in question would have been a sulpher precipitate, which
will form when the solution is stored cold.
It doesn't seem to hurt anything.
