Homebrew PCBs

I can get some ferric chloride cheap, a few dollars for a pound. It
is a bit old, sealed in two bags but it has stuck together a bit.
Not so much I can't break it up easily.

1. Is it likely to still be good? I just got a pound today but I
have the opportunity to buy a lot more cheaply.

2. Is there anything I can do to it to make it work better? Other
than the normal heating and agitating, I mean.
