Cutting Rockwool Slabs - possible or not?

[Grapefruitroop]

Hi yall!
Has anyone ever cutted a slab into 3 pieces to make some sort of Uni-Slabs?
I know the slab shouldnt be squished and to pay attention to dont breath or get some dust on me.....
Otherwise i should wait to get some blocks here but is not gona happen in the next days....so i was intertaining this idea...samurai split!
Thanks

Ive cut down the 3x3 blocks because they didnt fit in my cheap cups.

Good to know....but i ended up ordering some cubes cause i noticed that the slabs has horizontal fibers while the cubes are perpendicular.....if i had cutted the slab with a perpendicular cut i would def smoosh a bit the piece makin it loose its magic
Im transplanting some soon to be Mothers so i need to make sure the medium is PERFECT !
