I guess with me, I re-pressed a few NYX shadows with rubbing alcohol, and although it wasn't as "pretty" in the jar as when they're new, it seemed to still work just the same. Maybe if you like pressed blushes better, you can crush it entirely, and then take a small sample amount and try the alcohol method...if it still works well with the small amount re-pressed, then you can just re-crush and re-press the entire thing without worries...but if it doesn't, then you've only lost a small amount for the test? Either way, let us know how it goes, because there might be someone else out there who might benefit from what you ended up doing and how it turned out.
