I bought some P-phenylene Diamine from Photographers Formulary last week (in anticipation of Harvey's 777 developer tests). It arrived early this week, looking like moon rocks in the plastic jar. Big hunks of rock with one of them being near clear!. Is this correct? Does this stuff need to be ground down to use? I have never seen this material before and I am not sure what to expect.

Any help would be appreciated. I wrote to PF a couple days ago explaining what I received, but have got no answer. It would be nice to get this project started.
