Did my first pull and let the container sit in the freezer for a couple days because I was busy. Checked it last morning and put the lid on wrong where part of the rubber seal of a pyrex glass baking dish was submerged into the rubber.

Came back and found that the rubber had changed shape (became longer and bigger) yet none of it dissolved and the crystals look the same. Poured naptha out and dried the crystals, now wondering what to do with it.

I heard that the crystal matrix wouldn't form if the naptha were contaminated...
So what's my best bet here?

In other words, are my crystals unpure? Is a re-x necessary?

didn't you already ask pretty much the same question here?

Locked, since pretty much double question.
