Ice for Crystal

So I was out and about in the Frozen North, searching, albeit poorly, for Star Metal. I had a fire orb with me just in case I found something. I never did.
But as I wondered around lookin for Star Metal, my mind went back to the crystals I used to make the glass flasks, and I ran into some frost giants with crystals. Then a light went off. What if we could use ice in the grinder to make crystals?
Because it should be logical, I don’t see why we wouldn’t be. I think it’d be easier and way better to get crystals this way.
