Mag Flake question

[number1gsxxr]

I've got a bag of mag flake that has turned into a solid block from the humidity. It feels as hard as concrete. Is it still okay to use if I break it up with a hammer? I assume I'll have to pulverize it back to a powder in order to measure it out.

IIRC it is fine to chip away at the brick and use it. Just added moisture, but the mag part stays the same.

Awesome. I'd hate to just throw it away since this bag is already enough to last me a loooong time.
